Welcome to Processing
First Program
It allows to create an ellipse,
This center is on x=50 and y=50 and the diameter is 80.
​
Second Program
The ball follows the mouse and changes color when the mouse is pressed
Third Program
The last is automatic when the ball is thrown automatically and when it meets an edge it starts again in the other direction.
Final Program
