Mortgage Calculator in Java

Question

Can anyone help me figure out how to change my mortgage calculator to do the following?
Modify the mortgage program to display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list would scroll off the screen, but use loops to display a partial list, hesitate, and then display more of the list. Do not use a graphical user interface. Insert comments in the program to document the program. Here is the code I have currently.
import java.io.*;
import java.text.DecimalFormat;
public class MortgageRateWeek3Test
     public static void main(String[] args) throws IOException
          //Declaring and Constructing Variables
          int iTerm;
          double dInterest = 5.75;
          double dPayment, dRate, dAmount = 200000, dMonthlyInterest,dMonthlyPrincipal, dMonthlyBalance;
          DecimalFormat twoDigits = new DecimalFormat("$#,000.00");
                    //Calculations Retrieved from http://www.1728.com/loanform.htm on 9/14/05
                    dRate = dInterest / 1200;
                    iTerm = 360;
                    dPayment = (dAmount * dRate) / (1 - Math.pow(1 / (1 + dRate), iTerm));
                    dMonthlyInterest = (dAmount / 12) * (dInterest / 100);
                    dMonthlyPrincipal = (dPayment - dMonthlyInterest);
                    dMonthlyBalance = (dAmount - dMonthlyPrincipal);
                              // Output dPayment
                              System.out.println();
                              System.out.println("\tYour Monthly Payment is: " + twoDigits.format (dPayment));
                              System.out.println();
     public class monthlyInterest
          //Declaring Variables for monthlyInterest
          double dMonthlyInterest = 0.0;
          double dAmount = 0.0;
          double dInterest = 0.0;
               //Calculations for monthlyInterest
               dMonthlyInterest = (dAmount / 12) * (dInterest / 100);
          return dMonthlyInterest;
     public static double monthlyPrincipal()
          //Declaring Variables for monthlyPrincipal
          double dMonthlyPrincipal = 0.0;
          double dPayment = 0.0;
          double dMonthlyInterest = 0.0;
               //Calculations for monthlyPrincipal
               dMonthlyPrincipal = (dPayment - dMonthlyInterest);
          return dMonthlyPrincipal;
     public static double monthlyBalance()
          //Declaring Variables for monthlyBalance
          double dMonthlyBalance = 0.0;
          double dAmount = 0.0;
          double dMonthlyPrincipal = 0.0;
               //Calculations for monthlyBalance
               dMonthlyBalance = (dAmount - dMonthlyPrincipal);
          return dMonthlyBalance;
}

There are imports that aren't available to us, so no. nobody probaly can. Of course maybe someon could be bothered going through all of your code, and may spot some mistake. But I doubt they will since you didn't bother to use [c[b]ode] tags.
