Java compiler compiles the .java file(source code) by
generating the .class file comprising the bytecodes.
Bytecodes are platform independent and can be executed in a
system where JVM is installed.
JVM interpretes bytecodes into machine code depending upon
the underlying OS and H/W combination.
JVM provides a machine interface that does not depend on the
underlying OS and machine H/W architecture, thus making JAVA
as platform independent.
This makes java program as write-once run-anywhere.Only we
need to install compatible JVM, bcoz JVM is platform dependent.
