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);

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.

Project Description:

You are a real estate analyst who works for Mountain View Realty in the North Utah County area. You have consolidated a list of houses sold during the past few months and want to analyze the data. For a simple analysis, you will outline the data and use the Subtotal feature. You will then create two PivotTables and a PivotChart to perform more in-depth analysis.

 

Exp19_Excel_Ch07_Cap_Real_Estate

Project Description:

You are the office manager for a real estate company in northern Utah County. You tracked real estate listings, including city, agent, listing price, sold price, etc. Agents can represent a seller, a buyer, or both (known as dual agents). Your assistant prepared the spreadsheet structure with agent names, agent types, the listing and sold prices, and the listing and sold dates. You want to complete the spreadsheet by calculating the number of days each house was on the market before being sold, agent commissions, and bonuses. In addition, you will use conditional functions to calculate summary statistics. For further analysis, you will insert a map chart to indicate the average house selling price by city. Finally, you will create a partial loan amortization table and calculate cumulative interest and principal to show a potential buyer to help the buyer make decisions.

Purpose

This project provides you an opportunity to solve a comprehensive problem in firewall and virtual private network (VPN) implementation at various levels. You will play the role of an employee participating in network design and planning of a specific business situation.

Required Source Information and Tools

 

 

Web References: Links to web references in this Instructor Guide and related materials are subject to change without prior notice. These links were last verified on September 18, 2020.

 

 

The following tools and resources are needed to complete this project:

A web browser and access to the Internet to perform research for the project

(Optional) A tool for creating basic network diagrams, such as draw.io or Microsoft PowerPoint

Learning Objectives and Outcomes

Apply core competencies learned throughout the course to a single project.

Analyze and apply knowledge of firewalls, VPNs, and other network defense measures.

Demonstrate logical reasoning and decision-making skills.

Overall Project Scenario

Corporation Techs provides remote and on-site support to small and mid-size businesses. Clients use Corporation Techs’ services to solve problems involving malware removal, to manage data recovery and network issues, and to install hardware and software.

Due to recent developments, most technical representatives will begin working from home within the next six months. Because Corporation Techs provides 24/7 support, its systems and communications pathways must be fully operational at all times. In addition, the company has been experiencing unprecedented growth and is preparing to double its client-facing staff.

You are a junior network architect who is responsible for helping to plan and design network enhancements to create a more secure internal network, and to ensure secure remote access.

Deliverables

The project is divided into several parts. Details for each deliverable can be found in this document. Refer to the course Syllabus for submission dates.

Project Part 1: Network Design

Project Part 2: Firewall Selection and Placement

Project Part 3: Remote Access and VPNs

Project Part 4: Final Network Design Report

 

Project Part 1: Network Design

Scenario

The Corporation Techs’ current network consists of 1 web server (accessible by the public), 2 application servers, 2 database servers, 2 file and print servers, and 50 workstations. The web server runs Linux/Apache, the other servers run Microsoft Windows Server, and the workstations run Microsoft Windows. The network is connected through a series of switches, is not physically connected to other networks, and runs Internet Protocol version 4 (IPv4). The network is protected by a single border firewall. The senior network architect, whom you work for directly, has verified the company’s business goals and has determined the features and functions required to meet those goals.

The senior network architect has asked you to create a network design that includes the following components:

Current infrastructure elements

A logical topology that separates the Accounting and Sales departments

Redundant communications

Justification for continuing with IPv4 or upgrading to IPv6

Tasks

For this part of the project, perform the following tasks:

1. Conduct research to determine the best network design to ensure security of internal access while retaining public website availability.

2. Design a network configuration with physical and logical topologies. Identify major network elements (e.g., servers, switches, gateways) and their locations within the private and protected network segments.

3. Include a high-level plan that ensures communications are available 24/7.

4. Recommend whether to continue using IPv4 or upgrade to IPv6, and explain why.

5. Create a basic network diagram that illustrates the current network and enhancements. Include a few workstations to represent all workstations on the internal network. The diagram will be very high level at this stage and include only necessary details. You may use a software tool or simply pencil and paper. You will update this design later in the project.

6. Create a draft report detailing all information as supportive documentation.

7. Cite sources, where appropriate.
