Using Agile Techniques The Students Will Design A Personal Environment Network.

Project:

Using Agile Techniques the students will design an Personal Environment Network. This will involve each student identifying and classifying which components need addressing and how, using Agile development, this will be achieved. The final outcomes of this will a document or documents addressing these components, (Communication, planning, modeling, construction and deployment).

Organization and Flow:

• Project planning

• Use case development

• Requirement gathering

• Rapid design

• Code generation

• Testing

Area of work:

Using Agile Techniques the students will design an Personal Enviroment Network, This will involve in-class collaboration among the class students as they identify and classify which components need addressing and how, using Agile development, this will be achieved. The final outcomes of this

will a document or documents addressing these components, (Communication, planning, modeling, construction and deployment). The assignment will be further discussed during the lectures including time for students to discuss and work on the project.

Customer Requirements will be discussed in class

Overview:

A personal Environment Network is a network of ad-hoc device (cell phones or other WIFI wireless devices) that organize themselves into an active network to exchange information that is determined by each individual device. The application that allows the information exchange is responsible for security, look and feel and protocol. The underlining communication protocol is also part of the application. Furthermore, the application is capable of routing thru a node to get a link to a node outside a original nodes transmission range. These devices do not need any cell tower requirements, although it is possible.

According to Wikipedia these devices follow this definition:

A mobile ad hoc network (MANET), is a self-configuring infrastructure-less network of mobile devices connected by wireless links. ad hoc is Latin and means “for this purpose”. [1] [2]

Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network.

The growth of laptops and 802.11/Wi-Fi wireless networking have made MANETs a popular research topic since the mid 1990s. Many academic papers evaluate protocols and their abilities, assuming varying degrees of

mobility within a bounded space, usually with all nodes within a few hops of each other.

Different protocols are then evaluated based on measure such as the packet drop rate, the overhead introduced by the routing protocol, end-to-end packet delays, network throughput etc. Use case:

The user of the device sets their device to accept information from:

• Friends

• Ads by category

• Classmates (for example course 680)

• Device specifications in stores

• Home appliance devices

 

Classification of some simple use cases:

1) Item identification and location

2) ad-hoc social networking

3) ad-hoc phone services (vs. cellular phone service)

2. Your final complete solution report is due at 11:50 PM on Monday, 05/19/2014.

To begin

· Log on to your system and create a folder named Lab9 in your work space.

· Start the C++ IDE (Visual Studio) and create a project named Lab9.

LAB 9.1 – TRY IT: Working with Functions and Function Calls

Step 1: Add the tryIt6A.cpp program in your Lab6 folder to the project. Below is a partial listing of the source code.

1 // Lab 6 tryIt6A

12 /***** main *****/ 13 int main() 14 { int value = 2; 15 16 cout << “Hello from main.\n”; 17 printMessage(); 18 19 cout << “\nValue returned by tripleIt is ” 20 << tripleIt(value) << endl; 21 cout << “In main value now is ” 22 << value << endl << endl; 23 24 value = tripleIt(value); 25 cout << “In main value now is ” 26 << value << endl; 27 28 value = tripleIt(value); 29 cout << “In main value now is ” 30 << value << endl << endl; 31 32 cout << “Goodbye from main.\n”; 33 return 0; 34 } 35 36 /***** printMessage *****/ 37 void printMessage() 38 { 39 cout << “Hello from PrintMessage.\n”; 40 } 41 42 /***** tripleIt *****/ 43 int tripleIt(int someNum) 44 { 45 return someNum * someNum * someNum; 46 }

 Expected Output
  Observed Output

Step 2: Read the source code, paying special attention to the flow of control from main to the functions it calls and then back to main again. Notice what main passes to each function and what, if anything, the function return. Once you have done this, complete the “Expected Output” box in the table above, writing down what the program will display in the order it will be displayed.

Step 3: Now compile and run the tryIt6A.cpp program, and look at the output it creates. If the actual output matches what you wrote down, just place a checkmark in the “Observed Output” box. If it is not the same, write down the actual output.

LAB 9.2 – Using a void Function

Step 1: Remove tryIt6A.cpp from the project and add the fortunes.cpp program in your Lab6 folder to the project. Below is a copy of the source code.

1 // Lab 6 fortunes.cpp 2 // This fortune telling program will be modified to use a void function. 3 // PUT YOUR NAME HERE. 4 #include <iostream> 5 #include <cmath> 6 using namespace std; 7 8 // Function prototype 9 // WRITE A PROTOTYPE FOR THE tellFortune FUNCTION HERE. 10 11 /***** main *****/ 12 int main() 13 { 14 int numYears, 15 numChildren; 16 17 cout << “This program can tell your future. \n” 18 << “Enter two integers separated by a space: “; 19 20 cin >> numYears >> numChildren; 21 22 numYears = abs(numYears) % 5; // Convert to a positive integer 0 to 4 23 numChildren = abs(numChildren) % 6; // Convert to a positive integer 0 to 5 24 25 cout << “\nYou will be married in ” << numYears << ” years ” 26 << “and will have ” << numChildren << ” children.\n”; 27 28 return 0; 29 } 30 31 /***** tellFortune *****/ 32 // WRITE THE tellFortune FUNCTION HEADER HERE.

33 // WRITE THE BODY OF THE tellFortune FUNCTION HERE.

Step 2: Run the program to see how it works. What output do you get when you input the following values at the prompt? -99 14

________________________________________________________________________________

Step 3: Create a function that contains the fortune telling part of the code by doing the following:

· On line 9 write the prototype for a void function named tellFortune that has two integer parameters.

· On line 32 write the function header for the tellFortune function. Following that should be the body of the function. Move lines 22 – 26 of the program to the function body.

· Replace current lines 22 – 26 of main with a call to the tellFortune function that passes it two arguments, numYears and numChildren.

Step 4: Recompile and rerun the program. Enter -99 and 14 again. It should work the same as before.

Step 5: If your professor asks you to do so, print the revised source code and the output of executing it several times, using a variety of inputs.

LAB 9.3 – Modularizing a Program with void Functions

Step 1: Please see a copy of the completed areas2.cpp program and place it in your Lab6 folder. Name it areas3.cpp

// Lab 5 areas2-KEY.cpp

// This menu-driven program finds areas of squares,

// circles, and right triangles.

// It modifies the Lab 4 areas.cpp program to use a do-while loop.

// STUDENT NAME GOES HERE.

#include <iostream>

using namespace std;

int main()

{

const double PI = 3.14159;

double side, // Length of a side of a square

radius, // Radius of a circle

base, // Length of base of a right triangle

height, // Height of a right triangle

area; // Area of a square, circle, or right triangle.

int choice; // User’s menu choice

do

{

// Display the menu

cout << “\n\nProgram to calculate areas of different objects \n\n”;

cout << ” 1 — square \n”

<< ” 2 — circle \n”

<< ” 3 — right triangle \n”

<< ” 4 — quit \n\n”;

cin >> choice;

// Find and display the area of the user’s chosen object

if (choice == 1) // square

{ cout << “Length of the square’s side: “;

cin >> side;

area = side * side;

cout << “Area = ” << area << endl;

}

else if (choice == 2) // circle

{ cout << “Radius of the circle: “;

cin >> radius;

area = PI * radius * radius;

cout << “Area = ” << area << endl;

}

else if (choice == 3) // right triangle

{ cout << “Base of the triangle: “;

cin >> base;

cout << “Height of the triangle: “;

cin >> height;

area = .5 * base * height;

cout << “Area = ” << area << endl;

}

else if (choice != 4)

cout << “Choice must be 1, 2, 3, or 4.\n”;

} while (choice != 4);

return 0;

}

Step 2: Remove fortunes.cpp from the project and add the areas3.cpp program to the project.

Step 3: Modularize the program by adding the following 4 functions. None of them have any parameters.

· void displayMenu()

· void findSquareArea()

· void findCircleArea()

· void findTriangleArea()

To do that you will need to carry out the following steps:

· Write prototypes for the four functions and place them above main.

· Write function definitions (consisting of a function header and initially empty body) for the four functions and place them below main.

· Move the appropriate code out of main and into the body of each function.

· Move variable definitions in main for variables no longer in main to whatever functions now use those variables. They will be local variables in those functions. For example, findSquareArea will need to define the side variable and findCircleArea will need to define the radius variable. All of the functions that compute areas will now need to define a variable named area.

· Move the definition for the named constant PI out of main and place it above the main function.

· In main, replace each block of removed code with a function call to the function now containing that block of code.

Step 4: Compile the code, fixing any errors until it compiles without errors. Then test it. Make sure it runs correctly for all menu choices.

Step 5: If your professor asks you to do so, print the revised source code and the output of executing it , selecting each menu choice at least once.

LAB 9.4 – Using a Function that Returns a Value

Step 1: Remove areas3.cpp from the project and add the choice.cpp program in your Lab6 folder to the project. Below is a copy of the source code.

1 // Lab 6 choice.cpp 2 // This program illustrates how to use a value-returning 3 // function to get, validate, and return input data. 4 // PUT YOUR NAME HERE. 5 #include <iostream> 6 #include <cmath> 7 using namespace std; 8 9 // Function prototype 10 int getChoice(); 11 12 /***** main *****/ 13 int main() 14 { 15 int choice; 16 17 cout << “Enter an integer between 1 and 4: “; 18 19 // WRITE A LINE OF CODE TO CALL THE getChoice FUNCTION AND TO 20 // ASSIGN THE VALUE IT RETURNS TO THE choice VARIABLE. 21 22 cout << “You entered ” << choice << endl; 23 } 24 25 /***** getChoice *****/ 26 int getChoice() 27 { 28 int input; 29 30 // Get and validate the input 31 cin >> input; 32 while (input < 1 || input > 4) 33 { cout << “Invalid input. Enter an integer between 1 and 4: “; 34 cin >> input; 35 } 36 return input; 37 }

Step 2: Read through the code to see how it works. Notice that the getChoice function validates the input before returning it.

Step 3: Follow the directions given in the uppercase comments on lines 4 and 19-20. Then compile and run the program. When prompted for an input, use the data shown in the sample run below. You should get the same results.

Sample Run

Enter an integer between 1 and 4: 0

Invalid input. Enter an integer between 1 and 4: 9

Invalid input. Enter an integer between 1 and 4: 2

You entered 2

Step 4: Now make the getChoice function more versatile so it can validate that a choice is in any desired range, not just 1 – 4. Do this by carrying out the following steps:

· Add two integer parameters named min and max to the function header and modify the function prototype to agree with this.

· Revise the function so that it now validates that the input is between min and max. Remember to change the error prompt as well as the test condition of the while loop.

· Revise the line of code in main that calls the function so that it now passes two arguments to the function. Pass the values 1 and 4 to the function (though other values would work also).

Now recompile and rerun the program, again using the data from the sample run shown above. The program should produce the same results as it did before.

Step 5: If your professor asks you to do so, print the revised source code and the output of executing it with the sample run data.

Lab 9.5 – Modularizing a Program with Value-Returning Functions

For this lab exercise you will make additional improvements to the areas program you worked on in Lab 4, Lab 5, and earlier in this lab.

Step 1: In your Lab6 folder make a copy of your areas3.cpp file. Name it areas4.cpp

Step 2: Remove choice.cpp from the project and add the areas4.cpp program to the project.

Step 3: Copy the getChoice function you just wrote in the choice.cpp file for the Lab 6.4 exercise and paste it below the displayMenu function definition in the areas4.cpp file. Add a function prototype for the getChoice function at the top of the program where the other prototypes are located. Now, change the following line of code in main

cin >> choice;

to

choice = getChoice(1, 4);

This will ensure that choice is assigned a value between 1 and 4. Therefore the final else if can be removed from the if/else if statement that controls the branching. After doing this, test the program to make sure everything works so far, before going on to the next step.

Step 4: Now, make the findSquareArea, findCircleArea, and findTriangleArea functions into value-returning functions. They should each return a double value. Change their function headers and function prototypes to indicate this. Then, instead of having them print the area, have them return the area they have computed. Finally, change the call to each of these functions in main so that the value returned by the function call will be printed. For example, you will change

if (choice == 1)

findSquareArea();

to

if (choice == 1)

cout << “Area = ” << findSquareArea() << endl;

Step 5: Compile the code, fixing any errors until it compiles without errors. Then test it. Make sure it runs correctly for all menu choices.

Step 6: If your professor asks you to do so, print the revised source code and the output of executing it , selecting each menu choice at least once.

Lab 9.6 – Using Value and Reference Parameters

Step 1: Remove areas4.cpp from the project and add the swapNums.cpp program in your Lab6 folder to the project. Below is a copy of the source code.

1 // Lab 6 swapNums.cpp — Using Value and Reference Parameters 2 // This program uses a function to swap the values in two variables. 3 // PUT YOUR NAME HERE. 4 #include <iostream> 5 using namespace std; 6 7 // Function prototype 8 void swapNums(int, int); 9 10 /***** main *****/ 11 int main() 12 { 13 int num1 = 5, 14 num2 = 7; 15 16 // Print the two variable values 17 cout << “In main the two numbers are ” 18 << num1 << ” and ” << num2 << endl; 19 20 // Call a function to swap the values stored 21 // in the two variables 22 swapNums(num1, num2); 23 24 // Print the same two variable values again 25 cout << “Back in main again the two numbers are ” 26 << num1 << ” and ” << num2 << endl; 27 28 return 0; 29 } 30 31 /***** swapNums *****/ 32 void swapNums(int a, int b) 33 { // Parameter a receives num1 and parameter b receives num2 34 // Swap the values that came into parameters a and b 35 int temp = a; 36 a = b; 37 b = temp; 38 39 // Print the swapped values 40 cout << “In swapNums, after swapping, the two numbers are ” 41 << a << ” and ” << b << endl; 42 }

Step 2: Read the source code, paying special attention to the swapNums parameters. When the program is run do you think it will correctly swap the two numbers? Compile and run the program to find out.

Explain what happened. _________________________________________________________________

______________________________________________________________________________________

______________________________________________________________________________________

Step 3: Change the two swapNums parameters to be reference variables. Section 6.13 of your text shows how to do this. You will need to make the change on both the function header and the function prototype. Nothing will need to change in the function call. After making this change, recompile and rerun the program. If you have done this correctly, you should get the following output.

In main the two numbers are 5 and 7

In swapNums, after swapping, the two numbers are 7 and 5

Back in main again the two numbers are 7 and 5

Explain what happened this time. _________________________________________________________

______________________________________________________________________________________

______________________________________________________________________________________

You do not need to hand in the source code or output from this lab exercise.

Lab 9.7 – Complete Program

Step 1: Remove swapNums.cpp from the project and add the kiloConverter.cpp program in your Lab6 folder to the project. This file contains just a program shell in which you will write the programming statements needed to complete the program described below. Here is a copy of the file.

1 // Lab 6 kiloConverter.cpp 2 // This menu-driven program lets the user convert 3 // pounds to kilograms and kilograms to pounds. 4 // PUT YOUR NAME HERE. 5 #include <iostream> 6 using namespace std; 7 8 // Function prototypes 9 // WRITE PROTOTYPES FOR THE displayMenu, getChoice, 10 // kilosToPounds and poundsToKilos FUNCTIONS HERE. 11 12 /***** main *****/ 13 int main() 14 { 15 // DECLARE ANY VARIABLES MAIN USES HERE. 16 17 // WRITE THE CODE HERE TO CARRY OUT THE STEPS 18 // REQUIRED BY THE PROGRAM SPECIFICATIONS. 19 20 return 0; 21 } 22 23 /***** displayMenu *****/ 24 // WRITE THE displayMenu FUNCTION HERE. 25 // THIS void FUNCTION DISPLAYS THE MENU CHOICES 26 // 1. Convert kilograms to pounds 27 // 2. Convert pounds to kilograms 28 // 3. Quit 29 30 /***** getChoice *****/ 31 // THIS IS THE SAME FUNCTION YOU WROTE EARLIER IN THIS SET 32 // OF LAB EXERCISES. JUST FIND IT AND PASTE IT HERE. 33 34 /***** kilosToPounds *****/ 35 // WRITE THE kilosToPounds FUNCTION HERE. 36 // IT RECEIVES A WEIGHT IN KILOS AND MUST CALCULATE 37 // AND RETURN THE EQUIVALENT NUMBER OF POUNDS. 38 39 /***** poundsToKilos *****/ 40 // WRITE THE poundsToKilos FUNCTION HERE. 41 // IT RECEIVES A WEIGHT IN POUNDS AND MUST CALCULATE 42 // AND RETURN THE EQUIVALENT NUMBER OF KILOS.

Step 2: Design and implement a modular, menu-driven program that converts kilograms to pounds and pounds to kilograms. 1 kilogram = 2.2 pounds. The program should display a menu, accept and validate a user menu choice, get the amount of weight to be converted, call the appropriate function to do the conversion, and then print the returned result. The code should continue iterating to allow additional conversions to be done until the user enters the menu choice to quit. When the program runs it should look somewhat like the sample run shown here.

Sample Run

1. Convert kilograms to pounds

2. Convert pounds to kilograms

3. Quit

1

Weight to be converted: 4

4 kilograms = 8.8 pounds.

1. Convert kilograms to pounds

2. Convert pounds to kilograms

3. Quit

2

Weight to be converted: 10

10 pounds = 4.54545 kilograms.

1. Convert kilograms to pounds

2. Convert pounds to kilograms

3. Quit

3

Step 3: Once your program is written and compiles with no errors, thoroughly test it.

Step 4: If your professor asks you to do so, print the completed source code and the output produced by executing it , selecting each menu choice at least once.

CSE205 Object Oriented Programming And Data Structures Homework 1 :: 25 Pts assignment Help

CSE205 Object Oriented Programming and Data Structures Homework 1 :: 25 pts
1 Submission Instructions
Create a document using your favorite word processor and type your exercise solutions. At the top of the document be
sure to include your name and the homework assignment number, e.g. HW1. Convert this document into Adobe PDF
format and name the PDF file <asuriteid>.pdf where <asuriteid> is your ASURITE user id (for example, my ASURITE
user id is kburger2 so my file would be named kburger2.pdf). To convert your document into PDF format, Microsoft Office
versions 2008 and newer will export the document into PDF format by selecting the proper menu item from the File
menu. The same is true of Open Office and Libre Office. Otherwise, you may use a freeware PDF converter program, e.g.,
CutePDF is one such program.
Next, create a folder named <asuriteid> and copy <asuriteid>.pdf to that folder. Copy any Java source code files to this
folder (note: Java source code files are the files with a .java file name extension; do not copy the .class files as we do not
need those).
Next, compress the <asuriteid> folder creating a zip archive file named <asuriteid>.zip. Upload <asuriteid>.zip to the
Homework Assignment 1 dropbox by the assignment deadline. The deadline is 11:59pm Wed 26 Mar. Consult the online
syllabus for the late and academic integrity policies.
Note: not all of these exercises will be graded, i.e., random ones will be selected for grading.
2 Learning Objectives
1. Use the Integer and Double wrapper classes.
2. Declare and use ArrayList class objects.
3. Write code to read from, and write to, text files.
4. Write an exception handler for an I/O exception.
5. Write Java classes and instantiate objects of those classes.
6. Read UML class diagrams and convert the diagram into Java classes.
7. Identify and implement dependency, aggregation, inheritance, and composition relationships.
3 ArrayLists
3.1 Write code that creates an ArrayList<Integer> object named list and fills list with these numbers (using one or a
pair of for or while loops):
0 1 2 3 4 0 1 2 3 4
3.2 Consider the ArrayList<Integer> object named list containing these Integers:
list = { 1, 2, 3, 4, 5, 4, 3, 2, 1, 0 }
What are the contents of list after this loop completes?
for (int i = 1; i < 10; ++i) {
list.set(i, list.get(i) + list.get(i-1));
}
3.3 Write an enhanced for loop that counts how many numbers in an ArrayList<Integer> object named list are negative.
Print the count after the loop terminates.
3.4 Write a method named arrayListSum() that has one parameter pList which is an object of the class ArrayList
<Integer>. The method shall return the sum of the elements of pList.
3.5 Write a method named named arrayListCreate() that has two int parameters pLen and pInitValue. The method
shall create and return a new ArrayList<Integer> object which has exactly pLen elements. Each element shall be
initialized to pInitValue.
Arizona State University Page 1
CSE205 Object Oriented Programming and Data Structures Homework 1 :: 25 pts
3.6 Write a void method named insertName() that has two input parameters: (1) pList which is an object of ArrayList
<String> where each element of pList is a person’s name; and (2) a String object named pName. Assume the names
in pList are sorted into ascending order. The method shall insert pName into pList such that the sort order is
maintained.
3.7 Write a void method named arrayListRemove() which has two parameters: pList is an object of the ArrayList
<Integer> class and pValue is an int. The method shall remove all elements from pList that are equal to pValue.
4 Text File Input/Output
4.1 Explain what happens if you try to open a file for reading that does not exist.
4.2 Explain what happens if you try to open a file for writing that does not exist.
4.3 Name your source code file Hw1_1.java. Write a program that prompts the user for the name of a Java
source code file. The program shall read the source code file and output the contents to a new file named the same
as the input file, but with a .txt file name extension (e.g., if the input file is foo.java then the output file shall be
named foo.java.txt). Each line of the input file shall be numbered with a line number (formatted as shown below) in
the output file. For example, if the user enters Hw1_1.java as the name of the input file and Hw1_1.java contains:
//***************************************************************
// CLASS: Hw1_1 (Hw1_1.java)
//***************************************************************
public class Hw1_1 {
public static void main(String[] pArgs) {
}
public Hw1_1() {
}
}
then the contents of the output file Hw1_1.java.txt would be:
[001] //***************************************************************
[002] // CLASS: Hw1_1 (Hw1_1.java)
[003] //***************************************************************
[004] public class Hw1_1 {
[005] public static void main(String[] pArgs) {
[006] }
[007] public Hw1_1() {
[008] }
[009] }
Hint: to print an integer as shown above in a field of width 3 with leading 0’s use the printf() method with a format
specifier of %03d.
5 Exceptions and Exception Handling
5.1 Explain the difference between throwing an exception and catching an exception, i.e., explain what happens when an
exception is thrown and when one is caught?
5.2 Explain what a checked exception is. Give one example.
5.3 Explain what an unchecked exception is. Give one example.
5.4 Which type of uncaught exceptions must be declared with the throws reserved word in a method header?
5.5 Why don’t you need to declare that your method might throw an IndexOutOfBoundsException?
Arizona State University Page 2
CSE205 Object Oriented Programming and Data Structures Homework 1 :: 25 pts
5.6 Is the type of the exception object always the same as the type declared in the catch clause that catches it? If not,
why not?
5.7 What is the purpose of the finally clause? Give an example of how it can be used.
5.8 Which exceptions can the next() and nextInt() methods of the Scanner class throw? Are they checked exceptions or
unchecked exceptions?
6 Objects and Classes
6.1 Explain how an instance method differs from a class method (static method).
6.2 Explain what happens if we write a class named C but do not implement any constructors in C.
6.3 (a) In a static method, it is easy to differentiate between calls to instance methods and calls to static methods. How
do you tell them apart? (b) Why is it not as easy for methods that are called from an instance method?
6.4 Explain what happens when this application runs and why.
public class C {
private int x;
private String s;
public static void main(String[] pArgs) {
new C();
}
public C() {
x = s.length();
System.out.println(“x = ” + x);
}
}
6.5 Write the declaration for a class named C that declares: (1) a private int instance variable named mX; (2) a private
int class variable named mY initialized to 0; (3) a private int class constant named A which is equivalent to 100; (4)
a public int class constant named B which is equivalent to 200; (5) public accessor and mutator methods for mX
named getX() and setX(); (6) public accessor and mutator methods for mY named getY() and setY(); (7) a
constructor that has one int input parameter named pX which calls setX() to initialize mX to pX; (8) a default
constructor that calls C(int) to initialize mX to -1.
6.6 Continuing with the previous exercise, write the declaration for a class named Main that implements the main()
method. Within main() suppose we wish to instantiate a C object named cObj1 calling the default constructor.
Write the code to do this.
6.7 Continuing, write the code to instantiate another C object named cObj2 calling the second constructor to initialize
the mX instance variable to 10.
6.8 Continuing, within main(), are the following statements legal, i.e., do they compile? If so, explain what happens
when the statement is executed. If not, explain why the statement is illegal.
(a) int a1 = C.mX;
(b) int a2 = C.mY;
(c) int a3 = C.A;
(d) int a4 = C.B;
(e) cObj1.C(20);
(f) int a5 = cObj1.getX();
(g) cObj1.setX(20);
(h) cObj2.setX(cObj1.getX());
(i) int a6 = C.getX();
(j) C.setX(20);
(k) int a7 = cObj1.getY();
(l) cObj1.setY(20);
(m) int a8 = C.getY();
(n) C.setY(20);
Arizona State University Page 3
CSE205 Object Oriented Programming and Data Structures Homework 1 :: 25 pts
6.9 Continuing, suppose we add these two methods to the declaration of class C. For each assignment statement, if it is
legal (compiles) explain what happens when the statement is executed. For each assignment statement that is illegal
(syntax error) explain why the code is illegal.
public void f() {
mX = 0;
mY = 0;
}
public static void g() {
mX = 0;
mY = 0;
}
7 Object Oriented Design and UML Class Diagrams
7.1 Below is the code for a Java class named C. Draw the UML class diagram that corresponds to this code. There are
several free and open-source tools for drawing UML diagrams. Two reasonably simple and cross-platform (Windows,
Mac, Linux) tools are Umlet (http://www.umlet.com/) and Violet (http://alexdp.free.fr/violetumleditor). I have been
using Umlet for the diagrams I am drawing and I highly recommend it as it is very easy to quickly draw a
nice-looking class diagram. Using Umlet, you can export your diagram as an image file by selecting File | Export
As… on the main menu. I recommend you export the diagram as a .png image and then copy-and paste the .png
image into your word processing document.
public class C {
public static final int CONST1 = 100;
private int mX;
private double mY;
private String mZ;
public C() { this(0, 0, “”); }
public C(int pX, double pY, String pZ) { setX(pX); setY(pY); setZ(pZ); }
public int getX() { return mX; }
public int getY() { return mY; }
private String getZ() { return mZ; }
public void setX(int pX) { mX = pX; }
public void setY(int pY) { mY = pY; }
private void setZ(int pZ) { mZ = pZ; }
}
7.2 On the next page is a UML class diagram that shows several classes that are related in various ways. (a) What type
of class relationship, if any, exists between Course and Roster? If there is a relationship, modify the diagram to
indicate the relationship and label each end of the relationship with a multiplicity. (b) What type of class
relationship, if any, exists between Roster and Student. If there is a relationship, modify the diagram to indicate the
relationship and label each end of the relationship with a multiplicity. (c) What type of class relationship, if any,
exists between Student and UndergradStudent? If there is a relationship, modify the diagram to indicate the
relationship and label each end of the relationship with a multiplicity. (d) What type of class relationship, if any,
exists between Student and GradStudent? If there is a relationship, modify the diagram to indicate the relationship
and label each end of the relationship with a multiplicity. (e) What type of class relationship, if any, exists between
UndergradStudent and GradStudent? If there is a relationship, modify the diagram to indicate the relationship and
label each end of the relationship with a multiplicity.
Note: Draw this diagram in a UML diagramming tool such as Umlet or Violet and copy-and-paste your completed
diagram into your word processing document.

Assessing Security Culture Homework

/in , /by

Assessing Security Culture

This week we learned about security culture and how to promote it within organizations.

It’s important that all employees are aware of common security risks and treat security seriously. The majority of cyberattacks aim to exploit human weaknesses with methods like phishing.

For this reason, people are most often the weakest link in an organization’s security defenses.

Scenario

  • Employees at SilverCorp are increasingly using their own personal devices for company work.
  • Specifically, over half of all employees check their work email and communications via Slack on their personal mobile phones.
  • Another 25% of employees are doing other work-related activities using work accounts and work-related applications on their personal phone.
  • Allowing sensitive work information to be shared on employees’ personal devices has a number of security implications.
  • You must research these security risks and use the security culture framework to develop a plan to mitigate the concerns.

Instructions

Compose the answers to the following four steps on Word Document.

Step 1: Measure and Set Goals

Answer the following questions:

  1. Using outside research, indicate the potential security risks of allowing employees to access work information on their personal devices. Identify at least three potential attacks that can be carried out.
  2. Based on the above scenario, what is the preferred employee behavior?
    • For example, if employees were downloading suspicious email attachments, the preferred behavior would be that employees only download attachments from trusted sources.
  3. What methods would you use to measure how often employees are currently not behaving according to the preferred behavior?
    • For example, conduct a survey to see how often people download email attachments from unknown senders.
  4. What is the goal that you would like the organization to reach regarding this behavior?
    • For example, to have less than 5% of employees downloading suspicious email attachments.

Step 2: Involve the Right People

Now that you have a goal in mind, who needs to be involved?

  • Indicate at least five employees or departments that need to be involved. For each person or department, indicate in 2-3 sentences what their role and responsibilities will be.

Step 3: Training Plan

Training is part of any security culture framework plan. How will you train your employees on this security concern? In one page, indicate the following:

  • How frequently will you run training? What format will it take? (i.e. in-person, online, a combination of both)
  • What topics will you cover in your training and why? (This should be the bulk of the deliverable.)
  • After you’ve run your training, how will you measure its effectiveness?

This portion will require additional outside research on the topic so that you can lay out a clear and thorough training agenda.

3. We will specifically look at a tweet at index number 8. Assign a variable name to this tweet. For example: tweet8.

4. Check the data type of tweet8. Before changing the tweet8 to String type, firstly allow tweet8 to go through stemming. How many words in this sentence has been stemmed? What are the original form and base form respectively?

5. Remove the stop words from stemmed tweet8. Compare the original tweet8 and transformed tweet8. What are the stop words removed?

6. Reassign the 8th tweet to tweet8. Lemmatize the tweet8. What are the words has been lemmatized? What are the original forms and base forms respectively?

7. Change tweet8 to String type.

8. Use sentence tokenization function to segment tweet8. How many sentences are generated after tokenization?

9. Use word tokenization function to divide the words from the sentences. How many words have been generated? Display the words and sentences.

10. Use part of speech tagging function to assign POS tag to each word. Check the word and POS frequency. How many words have been assigned POS tags “VBD” (verb past tense)? What are the words being assigned with POS tags “VBD”?

11. Use name entity recognition function to detect name entities from this tweet. Does this function detect any name entities?

12. Use parsing function to parse this tweet. How many verb phrases (VP) are there? What components compose the last verb phrase? (If your parser does not work, you could skip this question)
