Interactivity with JButtons

JButton allows users to perform actions by clicking on it. We’ll explore how to create a button and make it respond to clicks.

import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("JButton Example");
        JPanel panel = new JPanel();
        JButton button = new JButton("Click Me!");

        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.out.println("Button was clicked!");
            }
        });

        panel.add(button);
        frame.add(panel);

        frame.setSize(400, 300);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}
