This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I see so many things wrong with that method...
1) you are missing the call to super.paint(g). Without it the previously painted contents will not be thrown away.
2) unless the Canvas is not part of a user interface or it's parent container has no layout manager the call to setSize does nothing.
3) setBackground shouldn't be called from the paint method but before it's ever called. This call could (it doesn't know for as far as I know but it could in the future) cause a repaint, which in your case would lead to a StackOverflowError.
In fact, only the if statement with contents is right.
