null layout means absolute positioning - you have to do all the work in your code. No layout manager to help you out.

Why don't you start by reading the Swing tutorial? There is a section that explains all about Layout Management as well as well what "absolute positioning" is. It also explains when you would use abolute positioning versus using a layout manager.
Generally the only time you would use it is when you need to support drag components to a random position.
The tutorial also has lots of other basic examples of using Swing components.

Yes, I browse a few different forums just to see if the questions are any different. – camickr Aug 24 '09 at 04:17
