Adding MouseListener to an Object

I'm new to Java so the answer to my question may be quite simple.
Basically my Main class is a JFrame. The JFrame contains an instance
of the "board" class. The board class contains several tiles
(Graphics). I need to be able to detect MouseListeners to the
tiles. I've done things with MouseListeners (adapters etc) with
standard swing components and not had trouble. Perhaps there is
something I don't know or I'm forgetting some of the basics.
Suggestions?

Thanks!

            tile newtile = new tile(i * 24, j * 24);
            tiles.add(newtile);
