Java solves the problem of platform-independence by using
byte code. The Java compiler does not produce native
executable code for a particular machine like a C compiler
would. Instead it produces a special format called byte
code. Java byte code written in hexadecimal, byte by byte,
looks like this:

CA FE BA BE 00 03 00 2D 00 3E 08 00 3B 08 00 01 08 00 20 08

This looks a lot like machine language, but unlike machine
language Java byte code is exactly the same on every
platform.
