CP2003 - Tutorial Five: Assignment Preparation and Introduction to GUI's

As usual, the first part of your tutorial involves finishing off any lingering tasks from last weeks tutorial. This is a seriously good idea as much of the last two weeks tutorials are directly applicable to the assignment.
Question two for this week involves a very brief introduction to graphical user interfaces (GUI's). In case you're wondering, we haven't covered these in lectures yet, we will begin GUI's at the end of next week. For your next assignment you will need to implement a GUI to act as a "front-end" for your encryption/decription code from the first assignment. For this reason you're required to download ExGui2.java and take a look around the source code, compile it and run it and get an idea of what it does. Don't worry too much if you don't understand all the code, but you should be able to figure out roughly which bits of the code perform the various functions. If you're feeling brave have a go at changing the title of the frame to be "Maria's Cyber Snack" instead of "Mark's...".
Now you have some time to work on your assignment - this is an ideal time because the tutor is their to give you guidance.
