A language is platform independant if it satisfies the
following 3 conditions :

1. It is compiled in a platform neutral manner i.e. object
code obtained after compilation doesn't contain any
Operating System specific information and doesn't follow
O.S. specification formats.

2. Language provides its own runtime environment for
execution of its applications.

3. Language provides comprehensive library to act as an
interface for O.S. services i.e. applications developed in
the language doesn't directly reference any O.S. specific
functionality.

Java follows all these conditions.
