This section provides a tutorial example on how to create a button with the javax.swing.JButton class.

Buttons are so easy to create with the javax.swing.JButton class. Here is a sample program:

/**
 * JButtonOk.java
 * Copyright (c) 2002 by Dr. Herong Yang, http://www.herongyang.com/
 */
import java.awt.*;
import javax.swing.*;
public class JButtonOk {
   public static void main(String[] a) {
      JFrame f = new JFrame("My First Button");
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      JButton b = new JButton("OK");
      f.getContentPane().add(b);
      f.pack();      
      f.setVisible(true);
   }
}

If you run this example, you will get:

Note: Clicking the OK button will trigger no actions, because no event listeners are added to the button component.

Sample programs listed in this section have been tested with JDK 1.3.1, 1.4.1, 1.5.0, and 1.6.0.
