Java runs with no errors, but no output displays?

Here's my assignment:

Purpose: Modify the mortgage program to display 3 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 for each loan and then list the loan balance and interest paid
for each payment over the term of the loan.
Use loops to prevent lists from scrolling off the screen.

Here's my code:

Does that code even compile?

kind regards,

I don't know how to tell if it compiles or not.

Do you know how to compile .java files? Read the manual that came with your IDE.

kind regards,

Jos

I have netbeans. I'm attending Univ of Phoenix, and since this is a Bachelor's level class, they only last 5 weeks. I'm having trouble learning a program in that amount of time. I appreciate the feedback though.

You're using Netbeans and it doesn't auto-indent?
Without some formatting it's rather hard to follow.
