need help for JOptionPane....

[keycoffee]

hi. I'm noe struggling with using JOptionPane. The question which I was assigned to do this.

You are to write a program that will accept a positive integer in the range 0 to 9999, i.e. the integer has a maximum of 4 digits.s input and then outputs the digits one per line.

The input/output must be via dialog boxes. The following are examples of the input/output you should produce:

I don't know how to put the output but I will type it down.

Homework 3(The title)

Enter a positive 4 digit number
[empty box where you can type the number] [Lets say 1234]

OK[Button] Cancel[Button]



Once click OK button, it will shows the next dialog

Homework3 Answer[Title]

The number was 1234
The digits are
1
2
3
4
OK[Button]

So far I got this codes


import javax.swing.*;
public class Homework3{

public static void main(String args[]){

String number;

number=JOptionPane.showInputDialog (null,"Enter a positive 4 digit");
JOptionPane.showMessageDialog(null,"The number was" + number);




}
}

So read the API specs for the String class to see what methods are available and pick the ones that are likely to help you.
