Action Listener Cpu Time

I'm looking for a comparison of cpu time for different kinds of interface. The main ideas I have are:

1. Have one event listener in the frame and check by x/y position which GUI object is interacted with via an if, else if structure.
2. Have an event listener for every GUI object.
3. Have one motion listener in the frame.

I know that motion listeners are the most cpu consuming, by how much? Between 1 & 2 what would the difference be with a few objects, with many objects?

    CPU consumption does not rely on which listeners you use or on how many objects, it depends on what the listeners actually DO. If you have a listener that does nothing more than output some data to a text field, it is not going to use much. If you create a listener that recalculates the entire lighting model of a 3D scene each time it fires, it is not going to do so well.
