If you want help with code, you'll have to provide an SSCCE that demonstrates what you're doing and where you're stuck. You have to be specific- what's not working?

Hello abraham.mikhail. Welcome to the forums.

We will need to see your code to be able to help you!

A tutorial on different loops can be found here - http://www.javaprogrammingforums.com...ava-loops.html

Here is a JOptionPane example:

Code Java:

---

import javax.swing.JFrame;
import javax.swing.JOptionPane;
 
public class OptionPane {
 
	  public static void main(String[] a) {
	    JFrame frame = new JFrame();
	    Object result = JOptionPane.showInputDialog(frame, "Enter something:");
	    System.out.println(result);
	  }
 
}
