At first the java source code is compiled and then it is
interpreted to a optimized set of executable statements.
After compiling the source code the bytecode is generated
which is same for all platforms i.e OS. This byte code
needs JVM(java virtual machine) to be interprated which is
defferent for different OS i.e platform.
Due to the byte code which is same for all JVM java is
explicitely known as platform independent language.

source code ---------> bytecode ----------> executable
compilation same interpration
for all by JVM
