在的Java Swing你如何管理面板允许多个面板的列表中进行选择？

import javax.swing.*;
import java.awt.*;

public class CardLayoutDemo {
    public static void main(String[] args) {
        JFrame frame = new JFrame("CardLayout Demo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 创建主面板和卡片布局
        JPanel mainPanel = new JPanel();
        CardLayout cardLayout = new CardLayout();
        mainPanel.setLayout(cardLayout);

        // 创建多个面板并添加到主面板中
        JPanel panel1 = new JPanel();
        JPanel panel2 = new JPanel();
        JPanel panel3 = new JPanel();
        mainPanel.add(panel1, "1");
        mainPanel.add(panel2, "2");
        mainPanel.add(panel3, "3");

        // 创建按钮并添加事件监听器
        JButton button1 = new JButton("Panel 1");
        button1.addActionListener(e -> cardLayout.show(mainPanel, "1"));
        JButton button2 = new JButton("Panel 2");
        button2.addActionListener(e -> cardLayout.show(mainPanel, "2"));
        JButton button3 = new JButton("Panel 3");
        button3.addActionListener(e -> cardLayout.show(mainPanel, "3"));

        // 将按钮添加到主面板中
        mainPanel.add(button1);
        mainPanel.add(button2);
        mainPanel.add(button3);

        // 将主面板添加到框架中
        frame.add(mainPanel);

        // 设置框架大小并显示
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}
