The System.out.println code is working. The second thing (timer.stop() and timer.start()) doesn't seem to be.
This is a Pong game. This checks if the ball is in the starting position. If "timer" hasn't been started, it will be in this position. Likewise for mouseExited.
EDIT: Figured it out...Just had to change code to || instead of &&.

subject: MouseEntered & MouseExited code seems not to be working...Problem fixed...by myself! :D
