Java's Swing is NOT easy to learn by yourself, and it's definitely not in the scope of being explained on a forum if you're not at least somewhat familiar with it. I'd say keep bugging your instructor, explain what you don't understand and work from there. Pick up a more general tutorial like basic Swing components or, as was suggested to you, general event listener tutorials. Read through those, get the code samples, run them, look through them and try to get a grasp of the basic structure.

Basically, though, a MouseListener is an Interface class that you need to extend. You need to implement it with your own code and write actions to happen when those events take place (that's your colour change) and then register it as a listener for the object you're trying to mouse-over. Instances of listener classes are automatically notified when events they're listening for take place over a class they're interested in, and this is done by the class itself which reacts to all such events. All you need to do is override methods responsible for the events you're listening for (in your case that's mouseEntere() and mouseExited()) and write your colour-changing code in them.

im not looking for homework service im looking for some examples of these kinds of programs
and looking for solutions of these problems
I already know the public void mouse moved and public void mouse exited but still i dont know how to change the color of the stop sign, ready and go sign when the mouse entered any solutions? please help me im begging you guys
