How JAVA achieves platform independence?
--------------------------------------------------------------------------------
Java is platform independent because of the consistent data
sizes at all the platforms on which Java code is run. The output
of a Java compiler is not an executable code it is bytecode.
bytecode is highly optimized set of instructions designed to be
executed by a virtual machine that the Java run-time system
emulates. As Java programs are interpreted, rather than compiled
it is much easier to run them in a variety of run-time
environments.
