You've gotta write all drawing stuff in the paint or draw method of an applet as far as I know... (or the paintComponent method of a JPanel...)

Not quite.

The_$hit, are you using HSA console or not?

Well, HSA console blows, so I don't include it in my generalizations :P

You can use this: http://java.sun.com/j2se/1.5.0/docs/api/java/awt/Graphics.html for example. There are others. Many others.

well, ehm, ok the Graphics class is an abstract class. think of it as a pen. .you dont draw on it.. u draw using it..

instead you draw on a component.. the best component for drawing is the java.awt.Canvas.

very much possible.. just define ur own function somehting like this:
public void drawMyShape(Graphics g) {
    // do drawing code here
}

and call it soemthing like this: drawMyShape(g); yea just pass it the Graphics object from the paint method..
