Thread: Need help with my code for calculating monthly payment on a loan

I can get it to enter amount and also enter rate and enter amount of years but can't get it to tell me the monthly payment for some reason. I know I am missing something.

import java.util.Scanner;
 
public class project5{
 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
 
		  //Print out the welcome screen
		  System.out.println ("Welcome to the Loan Calculator");
		  System.out.println();
 
		  double loanAmount;
		  double interestRate;
		  double months = 0;
 
		  String choice = ("y");
 
		  double numberYears;
 
		  while (choice.equalsIgnoreCase("y"))
		{
			   //read loan amount
			  Scanner sc = new Scanner (System.in);
			  System.out.print("enter amount");
			  loanAmount = sc.nextDouble();
 
			  //read interest rate
			  System.out.print("enter interest rate");
			  interestRate = sc.nextDouble();
 
			  //read number of years
			  System.out.print("enter number of years");
			  numberYears = sc.nextDouble();
 
			  //calculate the monthly payment
			  double monthlyPayment = loanAmount * interestRate / (1 - 1/Math.pow(1 + interestRate, months));
 
			  //display the monthly payment
			  System.out.println ("The monthly payment is:");
 
 
			  //see if the user wants to continue
			  System.out.print("continue? (y/n): ");
			  choice = sc.next();
			  System.out.println();
 
 
 
 
		}
 
 
	}
 
}

Okay I am not sure how to tell it to do that. Can you give me a tip on how to do it please?

Does anyone have an idea???
