how to output the result in jframe

[YingKang]

This code outputs the result in console. I want to implement a Swing JFrame, producing output readable by user. Do I have to change all my code if I want to use JFrame? Can anyone help? I am not familiar with JFrame at all. Thanks : )

import javax.swing.*;

     * for the hours of each, then prints paystubs for each and total
     * amount paid at the end.

So use a JTextArea, then, instead of using System.out.print or println, you use the JTextAreas append.
