Set action command for JButton

In this example we are going to see how to set action command for JButton component. This is a very important task when working in a Java GUI application, as most of the times you have to bundle a button with a specific action.

In short, to set action command for JButton one should follow these steps:

  • Create a class that extends JFrame and implements ActionListener.
  • Create a new JButton.
  • Use JButton.addActionListener to add a specific ActionListener to this component.
  • Use JButton.setActionCommand to add a specific command to this component.
  • Override actionPerformed method and use ActionEvent.getActionCommand to get the command of the button. Then you can customize this command as you wish.

Let’s see the code:

package com.javacodegeeks.snippets.desktop;

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class SetActionCommandForJButton extends JFrame implements ActionListener {

	private static final long serialVersionUID = 1L;

	public SetActionCommandForJButton() {

		// set flow layout for the frame
		this.getContentPane().setLayout(new FlowLayout());

		JButton button = new JButton("Java Code Geeks - Java Examples");

		//add Button

		//set action listeners for buttons

		// define a custom short action command for the button

		// add button to frame


	public void actionPerformed(ActionEvent ae) {
		String action = ae.getActionCommand();
		if (action.equals("Geeks")) {
			System.out.println("Button pressed!");

	private static void createAndShowGUI() {

  //Create and set up the window.

  JFrame frame = new SetActionCommandForJButton();

  //Display the window.





	public static void main(String[] args) {

  //Schedule a job for the event-dispatching thread:

  //creating and showing this application's GUI.

  javax.swing.SwingUtilities.invokeLater(new Runnable() {

public void run() {
