How do I scroll or wrap JTabbedPane tab layout?

JTabbedPane component tab layout policy of can be either set to JTabbedPane.SCROLL_TAB_LAYOUT or JTabbedPane.WRAP_TAB_LAYOUT. This layout policy will control the display of the tabs when the tabs cannot be displayed in one go. By the default the layout policy is set to JTabbedPane.WRAP_TAB_LAYOUT. Changing tab layout policy to JTabbedPane.SCROLL_TAB_LAYOUT makes the tabs scrollable. A button for scrolling left-right or up-down will be displayed in the tabbed pane.

package org.kodejava.examples.swing.tabbedpane;

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

public class TabbedPaneTabLayoutPolicy extends JPanel {
    public TabbedPaneTabLayoutPolicy() {
        initializeUI();
    }

    public static void showFrame() {
        JPanel panel = new TabbedPaneTabLayoutPolicy();
        panel.setOpaque(true);

        JFrame frame = new JFrame("TabbedPane Tab Layout Policy Demo");
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setContentPane(panel);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                TabbedPaneTabLayoutPolicy.showFrame();
            }
        });
    }

    private void initializeUI() {
        this.setLayout(new BorderLayout());
        this.setPreferredSize(new Dimension(400, 200));

        //
        // Creates a JTabbedPane with scroll tab layout policy
        //
        JTabbedPane pane = new JTabbedPane(JTabbedPane.TOP, JTabbedPane.SCROLL_TAB_LAYOUT);
        pane.addTab("One", createPanel("One"));
        pane.addTab("Two", createPanel("Two"));
        pane.addTab("Three", createPanel("Three"));
        pane.addTab("Four", createPanel("Four"));
        pane.addTab("Five", createPanel("Five"));
        pane.addTab("Six", createPanel("Six"));
        pane.addTab("Seven", createPanel("Seven"));
        pane.addTab("Eight", createPanel("Eight"));
        pane.addTab("Nine", createPanel("Nine"));
        pane.addTab("Ten", createPanel("Ten"));

        this.add(pane, BorderLayout.CENTER);
    }

    public JPanel createPanel(String title) {
        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        panel.add(new JLabel(title), BorderLayout.NORTH);
        return panel;
    }
}

Here is the screenshot of the code snippet created above. You can see that a button at the top right of the tabbed pane is added so that you can scroll to navigate the hidden tabs.
