Question

I have completed this program and it runs successfully; however, as part as an assignment I need to add this to it:

When it is working properly, add a while or do while loop to allow the user to run the CD calculation multiple times, entering a 0 initial deposit amount to exit. Change the prompt for the initial deposit amount to tell the user to enter 0 to exit.

I'm pretty lost at this point. I tried adding while and do-while, but I can't get either to work. Any help would be greatly appreciated. Thanks!

import java.util.Scanner;

public class CDvalue
{
public static void main(String[] args)
{

Scanner input = new Scanner(System.in);

System.out.print("Enter the initial deposit amount: ");
double deposit = input.nextDouble();

System.out.print("Enter annual percentage yield: ");
double annualInterest = input.nextDouble();
double monthlyInterest = (annualInterest / 1200.0);

System.out.print("Enter the maturity period (number of months): ");
int months = input.nextInt();

System.out.print(" Month CD Value ");

for(int i = 1; i <= months; i++)
{
deposit *= (1.0 + monthlyInterest);
System.out.printf("%5d%20.2f ", i, deposit);
}

}
}

Explanation / Answer

    import java.util.Scanner;

    public class CDvalue
    {
    public static void main(String[] args)
    {

    Scanner input = new Scanner(System.in);
    while(true)
    {
    System.out.print("Enter the initial deposit amount: (0 to exit):");
    double deposit = input.nextDouble();
    if((int)deposit==0) break;
    System.out.print("Enter annual percentage yield: ");
    double annualInterest = input.nextDouble();
    double monthlyInterest = (annualInterest / 1200.0);

    System.out.print("Enter the maturity period (number of months): ");
    int months = input.nextInt();

    System.out.print(" Month CD Value ");

    for(int i = 1; i <= months; i++)
    {
    deposit *= (1.0 + monthlyInterest);
    System.out.printf("%5d%20.2f ", i, deposit);
    }
    } //end while.
    }
    }
