Need Help with Assignment

Hi everyone, I am in a Java class and need help with my assignment. I am a little lost (well totally lost) . I am trying to create a mortgage calculator that will loop through three different loan terms (7 year at 5.35%, 15 year at 5.5%, and 30 year at 5.75%). I need to display an amortization table that will show principle, interest, monthly payment, and balance for each month of the loan term. My code is below - ant assistance would be much appreciated.

`import java.text.DecimalFormat;import java.io.*;public class Mortgage3 { public static void main(String[] args)throws IOException{ double[][] payment={{200000, 84, .0535, 0.0},{200000, 180, .055, 0.0}, {200000, 360, .0575, 0.0}}; //starts the array DecimalFormat decimal=new DecimalFormat ("#,##0.00"); //allows for the outcome to have 2 decimal points - barrowed from tony for (int i=0; i <payment.length; i++){ //sets the loop double loanAmount = payment[i][0]; //priniple amount double interestAmount = payment[i][2]; //interest amount on loan double loanTerms=payment[i][1]; //define the number of months for the loan double interestMonthly=payment[i][2]/12; //calcualtes the interest amount monthly double interestPower=Math.pow(interestMonthly +1, loanTerms); //calcualtes compounded interest double interestCompound=interestMonthly * (interestPower)/(interestPower - 1); //determine increment of interest double monthlyPayment=loanAmount*interestCompound; //this is the Prinicple[(interestMonthly)^360]/[(interestMonthly-1)] //displays monthly payment for each term loan and interest System.out.println(); System.out.println("************ McBride Financial Mortgage Calculator ******************"); //buffer below allows for payments/interest to be stored allowing user input to show the info in increments (ie. hitting any key to continue) BufferedReader payments = new BufferedReader(new InputStreamReader(System.in)); payments.readLine(); //prints payment/interest/balance System.out.println("Months----Payment---------Principal---------Interest----------Balance"); double principleAmount = 0.00; //amount of remaining principle double interestAmountMonthly = 0.00; //monthly interest amount double loanBalance = loanAmount; //sets loan balance equal to loan amount double paymentMonthly = 0;//sets monthly payment to zero int monthNumber = 0; //sets the loop to zero int counter = 0; //sets the loop to zero // calculates monthly paymeny / interest / principle - calculation taken from programmersheaven.com interestAmountMonthly = (loanBalance * interestMonthly); principleAmount = (loanBalance - interestAmountMonthly); paymentMonthly = (principleAmount + interestAmountMonthly); //creates the loop to display monthly principle/interest/loan balance 20 lines at a time monthNumber++; for ( monthNumber = 1; monthNumber <= 361; monthNumber++ ) { //calculates the amortization table interestAmountMonthly = (loanBalance * interestMonthly); principleAmount = (monthlyPayment - interestAmountMonthly); paymentMonthly = (principleAmount + interestAmountMonthly); loanBalance = (loanBalance - principleAmount); // displays the prinicple/interest/remaining balance in columns using tabs System.out.println( monthNumber + " \$" + decimal.format(monthlyPayment) +" \$"+ decimal.format(payment[i][1]) +" \$"+ decimal.format(interestAmountMonthly) +" \$"+ decimal.format(loanBalance)); counter++; //sets loop for numnber of lines displayed if (counter==20){ //only displays 20 lines at a time System.out.print("Press ENTER to continue:"); byte[] buffer = new byte[20]; //line taken from programmersheaven.com System.in.read(buffer); counter = 0; System.out.println("Months----Payment---------Principal---------Interest----------Balance"); }//closes the if statement }//closes the for loop }//close of array loop }//Close of Main }//close of class Mortgage2`
