Four Weeks Of CompSci

It has been one month since school started. The class that I am most out of tune with is AP CompSci. I am almost totally disconnected to this class.

So far I've been able to do a few things in JCreator. I copy and paste a code from one file into another and I make a chicken say "cluck-cluck". I think the only thing I've memorized is fill.oval and draw.oval. The rest of the codes slip my mind. Where are these codes coming from? What is java?

I honestly do not understand what this class is doing for me. I try to arrive fifth period eager to learn, but there is so much that I am missing.

Please tell me the context of all these codes. If I don't understand the context of what java is doing, this class means absolutely nothing to me. I'm copying and pasting codes. So far, JCreator has been nothing but rudimentary comprehension.
