Need help creating the response for this problem:

5.6 Warm up: Parsing strings (Java)

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)

  • Examples of strings that can be accepted:Jill, Allen
  • Jill , Allen
  • Jill,Allen

Ex:

Enter input string: Jill, Allen_x000D_

(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)

Ex:

Enter input string: Jill Allen_x000D_
Error: No comma in string_x000D_
Enter input string: Jill, Allen_x000D_

(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. (2 pts)

Ex:

Enter input string: Jill, Allen_x000D_
First word: Jill_x000D_
Second word: Allen_x000D_

(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)

Ex:

Enter input string: Jill, Allen_x000D_
First word: Jill_x000D_
Second word: Allen_x000D_
Enter input string: Golden , Monkey_x000D_
First word: Golden_x000D_
Second word: Monkey_x000D_
Enter input string: Washington,DC_x000D_
First word: Washington_x000D_
Second word: DC_x000D_
