You probably shouldn't be using classes at all.  When you are trying
to learn the basics of a language, you don't want to complicate things
further with classes.  Copying a program off the internet and trying
to modify it for your own purposes is usually going to be a lot more
work than writing the whole thing from scratch yourself.  In addition,
when you write the whole thing yourself, you'll have a better
understanding of how things work.
