مثال نوشته شده از CardLayout سر کلاس رو می تونید در ادامه مشاهده کنید:

public class MainWindow extends JFrame {

    public MainWindow() {
        super("My first JFrame");

        CardLayout cardLayout= new CardLayout();
        JPanel cardPanel= new JPanel(cardLayout);

        // center panel
        JPanel centerPanel= new JPanel();
        centerPanel.setLayout(new BoxLayout(centerPanel, BoxLayout.PAGE_AXIS));
        centerPanel.add(new JButton("Button 1"));
        centerPanel.add(new JButton("Button 2"));
        centerPanel.add(Box.createRigidArea(new Dimension(0, 10)));
        centerPanel.add(new JButton("Button 3"));
        cardPanel.add(centerPanel, "page1");
        // ===========================
        JPanel bottomPanel= new JPanel();
        bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.LINE_AXIS));

        bottomPanel.add(new JButton("Button 1"));
        bottomPanel.add(new JButton("Button 2"));
        bottomPanel.add(new JButton("Button 3"));
        cardPanel.add(bottomPanel, "page2");

        getContentPane().add(cardPanel, BorderLayout.CENTER);

        JPanel toolbarPanel= new JPanel(new FlowLayout());
        JButton preButton= new JButton("Pre");
        preButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                cardLayout.previous(cardPanel);
            }
        });
        toolbarPanel.add(preButton);
        JButton nextButton= new JButton("Next");
        nextButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                cardLayout.next(cardPanel);
            }
        });
        toolbarPanel.add(nextButton);
        getContentPane().add(toolbarPanel, BorderLayout.PAGE_END);
        
        pack();
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        setVisible(true);
