```
public class JTabbedPane
extends JComponent
implements Serializable, Accessible, SwingConstants
```
A component that lets the user switch between a group of components by clicking on a tab with a given title and/or icon. For examples and information on using tabbed panes see How to Use Tabbed Panes, a section in The Java Tutorial.
Tabs/components are added to a TabbedPane object by using the addTab and insertTab methods. A tab is represented by an index corresponding to the position it was added in, where the first tab has an index equal to 0 and the last tab has an index equal to the tab count minus 1.

The TabbedPane uses a SingleSelectionModel to represent the set of tab indices and the currently selected index. If the tab count is greater than 0, then there will always be a selected index, which by default will be initialized to the first tab. If the tab count is 0, then the selected index will be -1.

The tab title can be rendered by a Component. For example, the following produce similar results:
```
 // In this case the look and feel renders the title for the tab.
 tabbedPane.addTab("Tab", myComponent);
 // In this case the custom component is responsible for rendering the
 // title of the tab.
 tabbedPane.addTab(null, myComponent);
 tabbedPane.setTabComponentAt(0, new JLabel("Tab"));
 
```
The latter is typically used when you want a more complex user interaction that requires custom components on the tab. For example, you could provide a custom component that animates or one that has widgets for closing the tab.
If you specify a component for a tab, the JTabbedPane will not render any text or icon you have specified for the tab.

Note: Do not use setVisible directly on a tab component to make it visible, use setSelectedComponent or setSelectedIndex methods instead.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

    Parameters:
    
    index - the tab index which should be enabled/disabled

    Sets the component at index to component. An internal exception is raised if there is no tab at that index.
    
    Parameters:
    
    index - the tab index where this component is being placed

public void setDisplayedMnemonicIndexAt(int tabIndex,
                                        int mnemonicIndex)
```
    Provides a hint to the look and feel as to which character in the text should be decorated to represent the mnemonic. Not all look and feels may support this. A value of -1 indicates either there is no mnemonic for this tab, or you do not wish the mnemonic to be displayed for this tab.
    The value of this is updated as the properties relating to the mnemonic change (such as the mnemonic itself, the text...). You should only ever have to call this if you do not wish the default character to be underlined. For example, if the text at tab index 3 was 'Apple Price', with a mnemonic of 'p', and you wanted the 'P' to be decorated, as 'Apple Price', you would have to invoke setDisplayedMnemonicIndex(3, 6) after invoking setMnemonicAt(3, KeyEvent.VK_P).
    
    Note that it is the programmer's responsibility to ensure that each tab has a unique mnemonic or unpredictable results may occur.
    
    Parameters:
    
    tabIndex - the index of the tab that the mnemonic refers to
    
    mnemonicIndex - index into the String to underline
    
    Throws:
    
    IndexOutOfBoundsException - if tabIndex is out of range ( tabIndex < 0 || tabIndex >= tab count)
    
    IllegalArgumentException - will be thrown if mnemonicIndex is >= length of the tab title , or < -1

```
public void setMnemonicAt(int tabIndex,
                          int mnemonic)
```
    Sets the keyboard mnemonic for accessing the specified tab. The mnemonic is the key which when combined with the look and feel's mouseless modifier (usually Alt) will activate the specified tab.
    A mnemonic must correspond to a single key on the keyboard and should be specified using one of the VK_XXX keycodes defined in java.awt.event.KeyEvent or one of the extended keycodes obtained through java.awt.event.KeyEvent.getExtendedKeyCodeForChar. Mnemonics are case-insensitive, therefore a key event with the corresponding keycode would cause the button to be activated whether or not the Shift modifier was pressed.
    
    This will update the displayed mnemonic property for the specified tab.
    
    Parameters:
    
    tabIndex - the index of the tab that the mnemonic refers to
    
    mnemonic - the key code which represents the mnemonic
    
    Throws:
    
    IndexOutOfBoundsException - if tabIndex is out of range ( tabIndex < 0 || tabIndex >= tab count)

                              Component component)
```
    Sets the component that is responsible for rendering the title for the specified tab. A null value means JTabbedPane will render the title and/or icon for the specified tab. A non-null value means the component will render the title and JTabbedPane will not render the title and/or icon.
    Note: The component must not be one that the developer has already added to the tabbed pane.
    
    Parameters:
    
    index - the tab index where the component should be set
    
    component - the component to render the title for the specified tab
    
    Throws:
    
    IndexOutOfBoundsException - if index is out of range (index < 0 || index >= tab count)
    
    IllegalArgumentException - if component has already been added to this JTabbedPane
