Mouse detection at many positions

I am using Java with Swing and I want to detect mouse clicks at a number of locations (~200) in the view.

Should I use coordinates to ascertain where the click occurs (requiring searching through every location) or add multiple JPanels over each location and listen for mouse events for all of them?

If you have a great number of points, you can use a QuadTree datastructure to efficiently search through all points with a two-dimensional area as the search key. Although QuadTrees are not in the standard Java API, there are several Java implementations that you can easily find on the Internet.
