Introduction
 
This part of your main assignment should be done individually. This assignment consists of writing a program and demonstrating it or submitting it on Moodle.
 
NOTE: while you can do this using drag and drop in eclipse or some other java development environment you should be warned that;  I will put coding questions in the exam that assume you wrote this swing form yourself manually coding the listeners and attaching them to buttons. You are unlikely to learn how to do this if you use drag and drop GUI builders.
 
GENERAL INSTRUCTIONS
