Method

voidinstallPrefsHandler(final Preferences prefs, final String name, final JTabbedPane tabbedPane)
Installs a JTabbedPane preferences handler. 
int selectedTab = prefs.getInt(name, 0);
try {
    tabbedPane.setSelectedIndex(selectedTab);
} catch (IndexOutOfBoundsException e) {
tabbedPane.addChangeListener(new ChangeListener() {
    @Override
    public void stateChanged(ChangeEvent e) {
...
voidinstallPrefsHandler(Preferences prefs, String string, JTabbedPane tabbedPane)
install Prefs Handler 
throw new UnsupportedOperationException("Not yet implemented");
booleanisInTabbedContainer(Component c)
is In Tabbed Container 
Component parent = c.getParent();
while (null != parent) {
    if (parent instanceof JComponent && "TabbedContainerUI".equals(((JComponent) parent).getUIClassID())) 
        return true;
    parent = parent.getParent();
return false;
voidmoveTab(JTabbedPane tabPane, int srcIndex, int dstIndex)
As far as internal structure of JTabbedPane data model does not correspond to its visual representation, that is, component located on tab with index X is not located in the internal components array using the same index, we have to rearrange this array each time tab has been moved and repopulate/repaint JTabbedPane instance after that. 
int cnt = tabPane.getTabCount();
Component[] components = new Component[cnt];
for (int i = 0; i < cnt; i++) {
    components[i] = tabPane.getComponent(i);
String[] captions = new String[cnt];
for (int i = 0; i < cnt; i++) {
    captions[i] = tabPane.getTitleAt(i);
...
voidselectTab(JTabbedPane pane, String title)
Selects the tab with the specified title. 
int count = pane.getTabCount();
for (int i = 0; i < count; i++) {
    if (pane.getTitleAt(i).equals(title)) {
        pane.setSelectedIndex(i);
        break;
voidsetDefaultMnemonics(final JTabbedPane jtp)
set Default Mnemonics 
for (int i = 0; i < jtp.getTabCount(); i++) {
    switch (i) {
    case 0:
        jtp.setMnemonicAt(i, KeyEvent.VK_1);
        break;
    case 1:
        jtp.setMnemonicAt(i, KeyEvent.VK_2);
        break;
...
voidsetSelectComponentTab(Component component)
set Select Component Tab 
Component parent = component.getParent();
while (parent != null) {
    if (parent instanceof JTabbedPane) {
        JTabbedPane tabbedPane = (JTabbedPane) parent;
        tabbedPane.setSelectedComponent(component);
        break;
    component = parent;
...
voiduseTabToChangeFocus(Component comp)
use Tab To Change Focus 
Set<KeyStroke> strokes = new HashSet<KeyStroke>(Arrays.asList(KeyStroke.getKeyStroke("pressed TAB")));
comp.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, strokes);
strokes = new HashSet<KeyStroke>(Arrays.asList(KeyStroke.getKeyStroke("shift pressed TAB")));
comp.setFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, strokes);
