Java Swing Exit Button

In this post, I show you how to exit a Swing application when clicking on the exit button.

Java Swing Exit Button Code

In this example, we will have a button. When we click on the button, the application terminates.
package net.sourcecodeexamples.swingexamples.firstprograms;

import javax.swing.GroupLayout;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;

import java.awt.Container;
import java.awt.EventQueue;

 * Class to demonstrates When we click on the button, the application terminates.

public class QuitButtonExample extends JFrame {

 private static final long serialVersionUID = 1L;

    private void initializeUI() {

     JButton quitButton = new JButton("Quit");

        quitButton.addActionListener((event) -> System.exit(0));


        setTitle("Quit button");
        setSize(300, 200);

    private void createLayout(JComponent... arg) {

        Container pane = getContentPane();
        GroupLayout gl = new GroupLayout(pane);




    public static void main(String[] args) {

        EventQueue.invokeLater(() -> {
         QuitButtonExample quitButtonExample = new QuitButtonExample();
We position a JButton on the window and add an action listener to this button.
Here we create a button component. This constructor takes a string label as a parameter:
JButton quitButton = new JButton("Quit");
We plug an action listener to the button. The action terminates the application by calling the System.exit() method:
quitButton.addActionListener((event) -> System.exit(0));
The child components need to be placed into containers. We delegate the task to the createLayout() method:
