Hey John, How can I use this getColors methods in the public void
paintComponent(Graphics g)...to change the color of the balls...the
idea u gave me the other time, I couldn't use it...maybe if u could be
make it clearer..
private void getColors() {
		//if(randomColorMode){
			// this color is used to represent the
			// random color mode
			Random ran = new Random();
			int ranInt = ran.nextInt(4);

			switch(ranInt){
			case 0: ballColor = Color.white;break;
			case 1: ballColor = Color.blue;break;
			case 2: ballColor = Color.yellow;break;
			default: ballColor = Color.red;break;
			//}
		}


		if(ballColor.equals(Color.white)){
			ballColor = Color.white;
			backgroundColor = Color.black;
		}
		else if(ballColor.equals(Color.blue)){
			ballColor = Color.blue;
			backgroundColor = Color.black;
		}
		else if(ballColor.equals(Color.yellow)){
			ballColor = Color.yellow;
			backgroundColor = Color.black;
		}
		else{
			ballColor = Color.red;
			backgroundColor = Color.black;
		}
