For the second project, we will slightly increase the complexity and move on to 60 frames per second smoothly animated Pong clone. The Java topics covered include classes, interfaces, threads, try-catch blocks, method overloading vs. overriding and a much deeper look at object-oriented programming including writing and using our own classes. This project will also leave the reader competent with understanding the game loop, simple bouncing physics, playing sound effects and detecting game object collisions. Here is a picture of the simple but still a step-up Pong game.

If the Pong game doesn't seem very busy, then the next game will not only be the exact opposite but will also giv e you the knowledge to improve the first two games.
