@pakistanzeinab Yeah, I wasn't prepared, as I said :P

And I wanted to have fun and show people how it can be hard to make a simple modification to a code that you haven't worked on for a while .. because you lost the familiarity

[pakistanzeinab]

Hmm you took quite a while to explain such an easy thing no offense

This is all I did

public void undo() { int index = shapes.size() - 1; shapes.remove(index);

} and of course repainting in actionPerformed
