如何在Java中停止一次点击多个按钮(使用其他一些Jbutton)

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

public class ButtonExample {
    private static boolean isButtonClicked = false;

    public static void main(String[] args) {
        JFrame frame = new JFrame("Button Example");
        frame.setSize(300, 200);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JButton button1 = new JButton("Button 1");
        JButton button2 = new JButton("Button 2");

        button1.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                if (!isButtonClicked) {
                    isButtonClicked = true;
                    // 执行按钮1的操作
                    System.out.println("Button 1 clicked");
                }
            }
        });

        button2.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                if (!isButtonClicked) {
                    isButtonClicked = true;
                    // 执行按钮2的操作
                    System.out.println("Button 2 clicked");
                }
            }
        });

        JPanel panel = new JPanel();
        panel.add(button1);
        panel.add(button2);
        frame.add(panel);
        frame.setVisible(true);
    }
}
