Using a Canvas in a Panel

Question

Im doing a programming project for uni, and I need to know how to use the Graphics class, even although we have never covered it. The task is to create a game of hangman, and I am fine with every aspect of the program except when it comes to showing the actual hangman display. This figure must make use of the Graphics class (problem 1- ive no material on how to use it), and be inside a panel (which is in turn inside another panel). I was told today that I would need to create a Canvas in the panel I want to use for the Graphic, then place the graphic on the canvas (problem 2- same as problem 1).
Question is: how do I do ANY of this?
I would be really thankful for any help, because its due in pretty soon. Thanks.

Answer 1

I wrote this game a year ago, it uses 2 gifs for the gallow and the hangman, if you like this 2 gif i can email them to you, or you can change it to plain graphics .
