Nooblet here, I need to write this application, I got as far as making 6 
empty classes and originally needed to use swing, though since I need to 
learn swing I may just make it a console application and get less points 
for it. I need to be able of writing to disk the data (utilizing user 
input), deleting it when I want too and show I understand how classes 
work. While I understand extends, I don't quite understand what implement 
does.

Extends allows you to use the methods and variables of the class you 
extended (inheritance). Implement seems similar?

Anyways, since I only have 1 day to do this and I've been trying to do 
this for weeks, what are the classes available that will allow me to:

1.) Write a plain text file to disk?
2.) read the file?
3.) delete the file?
4.) check for the existence of the file?
5.) search for the file?
6.) compare files?

Where can I learn more about these specific classes? Any example code that 
is small and simple to read? :(
