it's slogan is WRITE ONCE RUN ANYWHERE

Features- 

Simple

• Secure

• Portable

• Object-oriented

• Robust

• Multithreaded

• Architecture-neutral

• Interpreted

• High performance

• Distributed

• Dynamic

OOP is a shortcut for object oriented programming

this type of programming methodology relies upon the Class concept, where these classes are created and used as a reusable objects to be used either inside the program an can be exposed out side the application boundary

the class is an object that has its owne members, methods, properties .....ets
