Need help figuring out what's wrong with my code!

Question

I am having a few problems with my code and can't see what I've done wrong. Here are my issues:
#1. My program is not displaying the answers to my calculations in the table.
#2. The program is supposed to pause after 24 lines and ask the user to hit enter to continue.
2a. First, it works correctly for the first 24 lines, but then jumps to every 48 lines.
2b. The line count is supposed to go 24, 48, etc...but the code is going from 24 to 74 to 124 ... that is NOT right!
import java.text.DecimalFormat; //needed to format decimals
import java.io.*;
class Mortgage2
//Define variables
double MonthlyPayment = 0; //monthly payment
double Principal = 200000; //principal of loan
double YearlyInterestRate = 5.75; //yearly interest rate
double MonthlyInterestRate = (5.75/1200); //monthly interest rate
double MonthlyPrincipal = 0; //monthly principal
double MonthlyInterest = 0; //monthly interest
double Balance = 0; //balance of loan
int TermInYears = 30; //term of loan in yearly terms
int linecount = 0; //line count for list of results
// Buffered input Reader
BufferedReader myInput = new BufferedReader (new
InputStreamReader(System.in));
//Calculation Methods
void calculateMonthlyPayment() //Calculates monthly mortgage
MonthlyPayment = Principal * (MonthlyInterestRate * (Math.pow(1 + MonthlyInterestRate, 12 * TermInYears))) /
(Math.pow(1 + MonthlyInterestRate, 12 * TermInYears) - 1);
void calculateMonthlyInterestRate() //Calculates monthly interest
MonthlyInterest = Balance * MonthlyInterestRate;
void calculateMonthlyPrincipal() //Calculates monthly principal
MonthlyPrincipal = MonthlyPayment - MonthlyInterest;
void calculateBalance() //Calculates balance
Balance = Principal + MonthlyInterest - MonthlyPayment;
void Amortization() //Calculates Amortization
DecimalFormat df = new DecimalFormat("$,###.00"); //Format decimals
int NumberOfPayments = TermInYears * 12;
for (int i = 1; i <= NumberOfPayments; i++)
// If statements asking user to enter to continue
if(linecount == 24)
System.out.println("Press Enter to Continue.");
linecount = 0;
try
System.in.read();
catch(IOException e) {
e.printStackTrace();
else
linecount++;
System.out.println(i + "\t\t" + df.format(MonthlyPrincipal) + "\t" + df.format(MonthlyInterest) + "\t" + df.format(Balance));
//Method to display output
public void display ()
DecimalFormat df = new DecimalFormat(",###.00"); //Format decimals
System.out.println("\n\nMORTGAGE PAYMENT CALCULATOR"); //title of the program
System.out.println("=================================="); //separator
System.out.println("\tPrincipal Amount: $" + df.format(Principal)); //principal amount of the mortgage
System.out.println("\tTerm:\t" + TermInYears + " years"); //number of years of the loan
System.out.println("\tInterest Rate:\t" + YearlyInterestRate + "%"); //interest rate as a percentage
System.out.println("\tMonthly Payment: $" + df.format(MonthlyPayment)); //calculated monthly payment
System.out.println("\n\nAMORTIZATION TABLE"); //title of amortization table
System.out.println("======================================================"); //separator
System.out.println("\nPayment\tPrincipal\tInterest\t Balance");
System.out.println(" Month\t Paid\t\t Paid\t\tRemaining");
System.out.println("--------\t---------\t--------\t-------");
public static void main (String rgs[]) //Start main function
Mortgage2 Mortgage = new Mortgage2();
Mortgage.calculateMonthlyPayment();
Mortgage.display();
Mortgage.Amortization();
ANY help would be greatly appreciated!
