/**
a Canvas is a graphic region where we can draw geometrical figures, such as a 
rectangle, an oval, etc ... The object g in the method paint() is a canvas.

Canvas class can extends from awt ( Abstract Windowing Toolkit ) class; as it does 
Graphics class (java.awt.Canvas like java.awt.Graphics)

The class Canvas contains the methods:
  public Canvas();
  public void addNotify();
  public void paint(Graphics g);
