I cannot seem to get the array to work and display the second and third loans, only the first one displays. Here is what I need to clarify the situation. I added the array to the program and it only works for the first loan. Can someone point me in the right direction.

Loan 1 15,000 12% 60 $333.67 $5,020.20 $20,020.20
Loan 2 15,000 10% 48 $xxx.xx $x.xxx $xx,xxx.xx
Loan 3 15,000 8% 36 $xxx.xx $x,xxx $xx,xxx.xx

Why do you have 2 programs in there (2 mains)? I don't see any Loan array in your code. can you mark the lines where you are printing the loan array? It is a little difficult to read.

I was using this as the array, but I think that I did it wrong. I removed the second main string, forgot I left it in, what should I do next?

class MortgageArray1
{
   	
{
	double amount = 15000;
	int[]term = {36, 48, 60};
	double[] rate = {.012, .010, .008};
	DecimalFormat twoDigits = new DecimalFormat("$000.00");

	System.out.println("With the loan amount of  " +twoDigits.format
	(amount));

	for (int i = 0; i < rate.length; i++)
	{

	System.out.print("for " + term[i] + " years");
	System.out.print("\tat a rate of " + rate[i]);
	double payment = (amount*(rate[i]/12))/(1-(Math.pow(1/(1+(rate
	[i]/12)),(term[i]*12))));

	System.out.println("\tThe monthly payment will be " +
	twoDigits.format(payment));

	}
  }

Now your class doesn't have any functions? How will this code ever execute? I'm sorry, either you have no clue what you are doing, or you are not able to express it well. This code, MortgageArray1, with a main function should probably work.
