如何为Java Swing按钮制作ActionListener

JButton button = new JButton("Click me");

class ButtonListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        // 在这里编写按钮点击后的逻辑代码
    }
}

button.addActionListener(new ButtonListener());

class ButtonListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        JOptionPane.showMessageDialog(null, "按钮被点击了！");
    }
}

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

public class ButtonExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Button Example");
        JButton button = new JButton("Click me");
        button.addActionListener(new ButtonListener());
        frame.getContentPane().add(button);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(300, 200);
        frame.setVisible(true);
    }

    static class ButtonListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
            JOptionPane.showMessageDialog(null, "按钮被点击了！");
        }
    }
}
