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

(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

Error: No comma in string

Enter input string: Jill, Allen

(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

First word: Jill

Second word: Allen

(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

First word: Jill

Second word: Allen





Enter input string: Golden , Monkey

First word: Golden

Second word: Monkey





Enter input string: Washington,DC
