Thanks to the time extension, I have time to review my code again. It looked fine to me when I completed it as I was probably too excited that I can finally go to bed in the end. When I look at my code again, I find that some of the methods are too long that it is complicated to read. Therefore, I improved my codes by creating other methods and declared some variables as global. I also added more comments. This way, it is easier to see how my program works. Other than that, formatting errors such as use of tabs are also corrected. Please find my refined code here.
I have tried to work on the extra credit portion, but after playing around with the codes, throwing more exceptions and doing some research on the web. I still have no idea how to make it work and so I decided to drop it.
This is the most challenging assignment by far. It took me a lot of time and efforts but I am glad that I have learned quite a lot from it.
