Controlling screen output

[ghostrider]

My program seems to run across the screen like carzy and I can not figoure out how to make it stop. Can anyone help me with this. Here is my program:

import java.text.DecimalFormat;
 
public class mortgagecalculatorwk3
{
public static void main (String[]args)
    {
/*Declares and intialize my varibles*/
    double P=200000; /*the initial amount of the loan*/
    double I =0.0575; /*annual interest rate(1 to 100 percent*/
    int    t=30;      /*length of the loan*/
    double mi=0;     /*monthly interest I/(12*100)*/
    double mp=0;   /*monthly payment*/
    double T=0;    /*declares monthly interest to be raised.*/
    double NM=0;    /*current monthly interest*/
    double c=0;        /*monthly payment-monthly interest rate*/
    double np=0;    /*new balance of loan*/
    double IP=0;    /* interest of the life of the loan*/
    int year=0;       /*number of years*/
    int month=0;    /*number of months*/
    int count=12;
 
 
/*Formulas that will be used are:*/
mi=(I/(12*100));
mp=(P*((I/12)/(1-Math.pow((1+(I/12)),-(t*12)))));
NM=P*mi;//monthly interest//
c=mp-NM;//monthly payment minus interest//
np=P-c;//balance of the loan to-date//
P=np;//the new balance of the loan//
 
System.out.println("Principal=$"+P);
System.out.println("Interest rate="+I*100);
System.out.println("Years of term="+t);
System.out.println("Number of payments="+t*12);
System.out.println("Monthly payment=$"+mp);
/*loop begins here*/
        for(year=1; year<=t; year++)
        {
        System.out.println();
        System.out.println("Press Enter key to continue.");
 
        for(month=1; month<=12; month++)
        {
        System.out.println("The monthly payment" + month + "year" + year + "Principle is:$ "+c);
        System.out.println("Interest for the life of the loan:$ "+NM);
        System.out.println("New balance of the loan:$  "+np);
        }//Exit month loop
 
        }//exit year loop
System.out.println();
System.out.println("Press Enter to continue");
 
    }
}
 
 

Please help me out here!

I assume after the message "Press Enter key to continue." you want the program to wait for the user to hit the enter key, try using Scanner, e.g.

import java.text.DecimalFormat;
import java.util.Scanner;
 
public class mortgagecalculatorwk3
{
public static void main (String[]args)
        {
Scanner s=new Scanner(System.in);
/*Declares and intialize my varibles*/
        double P=200000; /*the initial amount of the loan*/
        double I =0.0575; /*annual interest rate(1 to 100 percent*/
        int    t=30;    /*length of the loan*/
        double mi=0;    /*monthly interest I/(12*100)*/
        double mp=0;   /*monthly payment*/
        double T=0;    /*declares monthly interest to be raised.*/
        double NM=0;    /*current monthly interest*/
        double c=0;        /*monthly payment-monthly interest rate*/
        double np=0;    /*new balance of loan*/
        double IP=0;    /* interest of the life of the loan*/
        int year=0;        /*number of years*/
        int month=0;    /*number of months*/
        int count=12;
 
 
/*Formulas that will be used are:*/
mi=(I/(12*100));
mp=(P*((I/12)/(1-Math.pow((1+(I/12)),-(t*12)))));
NM=P*mi;//monthly interest//
c=mp-NM;//monthly payment minus interest//
np=P-c;//balance of the loan to-date//
P=np;//the new balance of the loan//
 
System.out.println("Principal=$"+P);
System.out.println("Interest rate="+I*100);
System.out.println("Years of term="+t);
System.out.println("Number of payments="+t*12);
System.out.println("Monthly payment=$"+mp);
/*loop begins here*/
                for(year=1; year<=t; year++)
                {
                System.out.println();
                System.out.println("Press Enter key to continue.");
                s.nextLine();
                for(month=1; month<=12; month++)
                {
                System.out.println("The monthly payment" + month + "year" + year + "Principle is:$ "+c);
                System.out.println("Interest for the life of the loan:$ "+NM);
                System.out.println("New balance of the loan:$  "+np);
                }//Exit month loop
 
                }//exit year loop
System.out.println();
System.out.println("Press Enter to continue");
 
        }
}
