What are the Java file's extensions.

In Java we have only two extension files. They are 

•  ".java" extension file it called source code which is developed by developer.
•  ".class" extension file it is called compiled code contains bytecode which is generated by compiler from source code.

Like in 'C' or 'C++', in java we do not have executable file means ".exe" extension files. More over in java, the compiled code is not machine language; instead it is an intermediate code, named as "bytecodes" stored in a new file with an extension ".class". This code is generated by java compiler and is only understandable by JVM.
