How to find out which object currently has focus

Question

I have a few TextFields in my Frame. I want to know which TextField currently has focus. How can I find this information?

Answer 1

KeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusOwner() 

Answer 2

JFrame.getFocusOwner() (inherited from Window.getFocusOwner()) ought to return a reference to the component with focus. getMostRecentFocusOwner() might also be of interest.
