Scribble - a demonstration of graphical output on a Canvas class.

This project is part of the material for the book

   Objects First with Java - A Practical Introduction using BlueJ
   Fifth edition
   David J. Barnes and Michael Kölling
   Pearson Education, 2012

This project is discussed in chapter 5.

This project provides some short graphical demos in the DrawDemo class.

This project provides great scope for extension. The Canvas class does 
not usually need to be changed. It may be best to treat it as a library
class (open the editor and switch to "documentation" view).

Other classes can be changed or added. The book contains suggestions 
for various exercises.
