Platform Independence means a program can run on any OS and
h/w architecture.
To achieve this, JAVA adapted d concept of byte code, that
is converted from source code, n this byte code can be
executed on any machine in d world.

To clearly understand, lets take C compiler as an exaple.
In C, the source code can be compiled in differnt OS like
Windows, DOS, Linux, etc. by using differnt compilers for
differnt OS ,BUT in migrating from one OS to other, the OS
added some features of its own n d result would be little
bit or even completely changed , e.g., if we
use "graphics.h" in C, it will not run on Win7....
thus C is'nt platform independent.

n Remind that Platform Independence also includes that, a
program can run on any H/W architecture i.e. on any
processor...
