TitleCanvas.java:-

height = getHeight();
}
public void paint(Graphics g) {
g.fillRect(0, 0, width, height);

g.drawImage(image, width / 2 - (image.getWidth() / 2), height / 2 - (image.getHeight() / 2), 0);
g.drawString("Nirmal Ganesh", 1, 1, 0);
}
}

The variable "Mode" used in Program is showing direction of ball. That is well explained in Image below:

The following are the Required image files for this Game which must be put into "res" folder:- back.jpg:- title.jpg:-
Just compile this program & use it.

The screenshot below may help you little bit.
