I'm reading Sams teach yourself Java in 24 hours and I'm on page 201.
I just want to know what a jar file is, what they're used for and how to use
them.

Jar is an archive of byte-compiled java code. It's a useful format to distribute libraries etc.

do jar files contain other files inside of them? like java and class files?

on a linux or macos system you can use unzip from the command line

I don't know if anything is that easy on windows

If you are meaning to use java to access csound, the jar file which you'll
want to include in your classpath is "csnd.jar".  With that in your project,
you can access many of the functions that csound exposes (via its
application programming interface or API) that make it possible to run
csound from your chosen language - in your case java.

While you can look inside the jar file by unzipping it, what you'll see in
csnd.jar is mostly JNI (java native interface) code which bridges from java
to the native "c" functions that comprise the real csound code.  JNI is
pretty arcane looking to a beginning java programmer, so maybe it's best to
leave its internals be until you are more confident.

There are some examples in the "examples/java" directory of your csound
installation.  Also, you can follow these links for some other examples:

http://en.flossmanuals.net/csound/ch063_the-csound-api/
http://csounds.com/node/364
http://www.csounds.com/journal/2006summer/SliderDemo.html

Steven Yi's csound front end "blue" is written in java and is open source at
sourceforge; that's a big league example of integrating csound from java.

Your right, I wanna know how Java can enhance my csound.
Teach yourself Java in 24 hours is my first Java book and I'm a pretty
dedicated reader now.

What is an API? what is it used for? do you have to download and install it?
Java is talking to C using JNI code? native?
how can I learn JNI code? whats a good Java book for a beginner like me?
I keep reading the beginner books but I'm getting for confident with
programming in general.
