Java Program

The goal of this assignment is to develop an event-based game. You are going to develop a Pong Game.

The game board is a rectangle with a ball bouncing around. On the right wall, you will have a rectangular paddle (1/3 of the wall height). The paddle moves with up and down arrows. Next to the game board, there will be a score board. It will show the count of goals, and count of hits to the paddle. In the beginning of the game, the paddle will be on the center of the right wall.

You can develop a two-player game, and it will count for extra 2 points bonus.

You can arrange the color and the style of the board/paddle/ball/Score Board as you prefer.
