Using function keys to select a certain tab in a JTabbed pane

I want to use the function keys (F1,F2,F3 etc.) to select certain tabs
within my JTabbed pane. I know how to use keylistener and can use it to
detect the actual keys being pressed but i can't figure out how to change
the tabs according to the button pressed.

Can someone help me?

You first mention keys, then you mention "button". Are you using "button"
as a synonym for "key", or are you asking about also using something like
a JButton to switch the tab?

I was referring to the function keys such as F1, F2, F3 etc. I would also
like to use JButtons external to the JTabbed pane to switch between tabs
too. Any ideas?

For the function keys, you will need to map the Keystroke to the tab that
you want to select. For this, I would use a java.util.Map.

For buttons, I would use a "client property" on the button that would
indicate what tab to switch to. Then you could use a single Action for
all of the buttons. It would get the client property from the source of
the event and use that to switch the tabs.

Add a KeyListener to your JTabbedPane and then (for example with 2 tabs):

if (e.getKeyCode()==KeyEvent.VK_F1)
getJTabbedPane().setSelectedIndex(0);
else if (e.getKeyCode()==KeyEvent.VK_F2)
getJTabbedPane().setSelectedIndex(1);

or setSelectedComponent(Component c)
