Automated game of pong using Java Robot class

Using the Java Robot class, I have written a small utility that plays an automated game of pong against the computer.

It constantly monitors the left side of the game, and when a ball enters the field, it moves the mouse cursor to the position of the ball.

Demo video:

This is a simple introduction to image-recognition and mouse-movement in Java. Feel free to use the code, optimize or improve.

Usage of the RobotPong object::

Create an object using the coordinate of the part of the screen that needs to be monitored.
Start the object using the start() method, this will start the thread containing the object.
It is possible to run multiple threads, each playing their own game of pong.

The game itself can be found at the MegaFunGames webpage.

The code:
