Tha Java compiler translates Java source code into JVM bytecode (files 
with ".class" at the end of the name).  This is a bit similar to machine 
code, just for a different processor.  At runtime the JVM will interpret 
the bytecode.  But:

Interpretation is relatively slow so the JVM has a just in time compiler 
(JIT) that translates bytecode to machine code for the platform just 
before execution and then lets the CPU execute it.

There are a lot more details especially about what the JVM does but if 
you are confused we should probably stick with the simple things and 
make sure you understood them before moving further. :-)

Cheers
