Java/ApComputerSci., User input programs Options

[SkaironFrenzy]

{OK i'm pretty much new to Java and the computer language thing, but I do understand the fundamentals.}

Due:Wednesday, 21,2005

Problem:

Write an application program that inputs one number consisting of four digits from the user; separates the number into its individual digits and prints the separated digits from one another. For example, if the user types in the number 4239, the program should print 4 2 3 9.(hint:Use Mod(%) and Division(/).

Ok this is what I got so far:

import javax.swing.JOptionPane;

public class Separate
{
public static void main(String[] args)
{
String number;
int numberOne;
double mod;
double division;

number=JOptionPane.showInputDialog("Enter 4 numbers");
numberOne= Integer.parseInt(number);


System.exit(0);
}
}

(I tried putting a code box but it screwed up the code.)
Its just the foundation. I cant figure out the rest to separate the numbers. Thanks you all for your help.
