asteroids revisited

Sorry about the long-long code. I rewrote the code from a more object-oriented approach. Since I'm new to OOP and java I couldnt do firing. Any comments and object oriented firing code welcome.
// Proto-Asteroids 0.1 OOP
// Started by REAS
// Acceleration by nashdj
// Firing, deceleration by REAS
// just tried to add a sample of one asteroid and the destruction of the ship, Anurag.

// Mouse-based Asteroids, navigate by pressing the mouse
// Fire with the 'space bar'.
// fire asteriods and avoid them to avoid destruction.
