When Java Code is compiled a byte code is generated which
is independent of the system. This byte code is fed to the
JVM (Java Virtual Machine) which is resided in the system.
Since every system has its own JVM, it doesn't matter where
you compile the source code. The byte code generated by the
compiler can be interpreted by any JVM of any machine.
Hence it is called Platform independent Language.
