Object Oriented:

    Java is an object oriented programming language, this means java programs use objects and classes,
A) Standalone programs (Applications)
B) Applets
    
      => Both programs are prepared with the " .class" extension.
      => Both require JVM to execute these Byte code.

Applets:-
======
   Applets are the programs written specially for the distribution over a network. These programs
 contain information delivered to the world and involve user interaction. For example order entry
 form, registration form mailing etc.

Applications:-
=========
    Applications are system programs i.e; these programs run in the background and don't
 involve user interaction. For example server
administration, security manager etc.
