I need a very simple program of a mortgage calculator to accomplish the following:
Write the program in Java (with a graphical user interface) and have it calculate and display the mortgage payment amount from user input of the amount of the mortgage and the user's selection from a menu of available mortgage loans:
- 7 years at 5.35%
- 15 years at 5.5%
- 30 years at 5.75%
Use an array for the mortgage data for the different loans. Read the interest rates to fill the array from a sequential file. Display the mortgage payment amount followed by the loan balance and interest paid for each payment over the term of the loan. Add graphics in the form of a chart. Allow the user to loop back and enter a new amount and make a new selection or quit. Please insert comments in the program to document the program.
If possible, I need to keep the program basic and very simple. Also, I need a flowchart to go with it. And I need to have it by Monday, 02/28/2011.
