CardLayout を使用すると、Swing での「戻る/進む」ボタンの実装をどのように簡素化できるでしょうか?

import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import javax.swing.AbstractAction;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

// ...

    // Create a CardLayout manager
    CardLayout cards = new CardLayout();

    // Create an array of panels to be managed by the CardLayout
    JPanel[] panels = new JPanel[] {
        new JPanel(),
        new JPanel(),
        new JPanel()
    };

    // Add the panels to the CardLayout manager
    for (int i = 0; i < panels.length; i++) {
        cards.add(panels[i], "panel" + i);
    }

    // Create a JPanel to hold the back and forward buttons
    JPanel controlPanel = new JPanel();

    // Add the back and forward buttons to the control panel
    controlPanel.add(new JButton(new AbstractAction("\u22b2Prev") {

        @Override
        public void actionPerformed(ActionEvent e) {
            cards.previous(panels);
        }
    }));
    controlPanel.add(new JButton(new AbstractAction("Next\u22b3") {

        @Override
        public void actionPerformed(ActionEvent e) {
            cards.next(panels);
        }
    }));

    // Add the CardLayout and control panel to the frame
    frame.add(cards, BorderLayout.CENTER);
    frame.add(controlPanel, BorderLayout.SOUTH);
