Making a program with this code.

There is a power point presentation I found that has an example of a program I really want to make, and it supplies all the code, but I'm a bit confused as to where each slide of code goes and how many actual .java files I have to make and what code goes into each file!

The power point presentation is here:

The program is from slides 26 to 53.

It would be great if anyone could have a look and just let me know what .java files I'll need and what slides go where.
Thanks.
