希望在JFrame的同一面板中为多个按钮添加功能

JFrame frame = new JFrame("多个按钮功能");
frame.setLayout(new FlowLayout());

JButton button1 = new JButton("按钮1");
button1.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        // 添加按钮1的功能代码
    }
});
frame.add(button1);

JButton button2 = new JButton("按钮2");
button2.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        // 添加按钮2的功能代码
    }
});
frame.add(button2);

// 创建并添加其他按钮...

frame.setSize(300, 200);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
