Thread: Having trouble with my program, can someone please help?

//Imports the scanner utility
import java.util.Scanner;

public class ComputeLoan1
{

//Calls the method for variables to be calculated
public static double calculations(double loanAmount, double monthlyInterestRate, int numOfYears)
{

//Declares calculations as monthlyPayment
double monthlyPayment = (loanAmount * monthlyInterestRate / (1
- 1 / Math.pow(1 + monthlyInterestRate, numOfYears * 12)));

//Value that is returned to the main method
return monthlyPayment;

}//Closes the calculations method

//Final method used to output users calculations
public static void finalMethod(String[] args)
{

//Displays results
System.out.println("The monthly payment is " + (int)(monthlyPayment * 100) /100.0);

}//Closes the finalMethod


//Main method
public static void main(String[] args) {


//Declarations
double loanAmount = 0;
double annualInterestRate = 0;
double monthlyInterestRate = 0;
int numOfYears = 0;
double calculations;

//Creates a scanner for input from keyboard
Scanner input = new Scanner(System.in);

//Greeting to the user
System.out.println("Welcome to Kentucky Credit Union Loan Calculator!");
System.out.println("This program is used to help calculate the monthly loan amount.");
System.out.println("");


//Prompts the user for input
System.out.print("Please enter the loan amount: $");
loanAmount = input.nextDouble(); //Accepts input from user and stores it in a variable

//Enter yearly interest rate
System.out.print("Enter yearly interest rate, for example 7.25: ");
annualInterestRate = input.nextDouble();

//Obtain monthly interest rate
monthlyInterestRate = annualInterestRate / 1200;


//Prompts the user for input
System.out.print("Please enter length of the loan in years as an integer, for example 5: ");
numOfYears = input.nextInt();

} //Closes the main method


}//Closes the class

This is the error I get:

Documents\JCreator LE\MyProjects\ComputeLoan1\src\ComputeLoan1.java:2 5: cannot find symbol
symbol : variable monthlyPayment
location: class ComputeLoan1
System.out.println("The monthly payment is " + (int)(monthlyPayment * 100) /100.0);

the monthlyInterestRate = annualInterestRate / 1200; is correct. I used to know why you do it this way, but I forgot. It's how it is in my java programming book too.

this is what the program is suppose to do:

Your application will calculate the monthly payments due on a loan. The user will input the loan amount, the interest rate, and the loan's term (time to repay).

You will accept input in the main method. You will use a separate method (other than main) to calculate the payment. You will use a third method to output the result. The third method (output) can be called from either the main method or the calculation method. Here is the formula you will use to calculate the payment:

Payment Formula

Ty very much for your help. I got it figured out. Ty
