Instructions: (Week 2)Write a Java program using a graphical user interface that calculates and

displays the mortgage payment amount from user input of the amount of the mortgage, the term of the

mortgage, and the interest rate of the mortgage. Allow the user to enter new data for new results.

Insert comments in the program to document the program. (Week 3)Modify the mortgage program to

allow the user to input the amount of a mortgage and then select from a menu of mortgage loans:

7 year at 5.35%, 15 year at 5.50%, and 30 year at 5.75%. Use an array for the different loans.

Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment

over the term of the loan. Allow the user to enter a new amount and make a new selection, with

resulting new values.

Allow user to exit if running as an application (can't do that for an applet though).
