Whenever we compile the java source code it becomes
transform into an intermediate code(known as "Byte
Code"),unlike other languages,"ByteCode"(.Class file) is
platform independent code.Then u can run the Byte Code on
any Platform(OS)either it is Linux,Mac or Windows..But d
reality is that the ByteCode(.class file)is run by the Java
Interpreter which in turn invokes the JVM(Java Virtual
Machine) which is differ for the different OS. And the
output of JVM is machine dependent code..[AND THE MOST
SECRET:--JAVA IS NOT PLATFORM INDEPENDENT IF THERE IS NOT
THE DIFFERENT JVM FOR DIFFRENT OS...AND PLUS WE NEED NOT TO
INSTALL JVM MANUALLY ..IT IS INBUILT IN ALL OS..]
