Java is an OOPS language and it is not a pure OOPS Language.

 The main OOP features are:
 Encapsulation

 Inheritance
 Polymorphism
   
 Abstraction
 All predefined types must objects
 All operations are performed by sending messages to objects
   
 All user defined types must objects.

JAVA is not because it supports Primitive data type such as int, short, long ,char, byte, double, float  is used which are not objects.


 
Java does not support multiple inheritances directly.



Java supports static variables that are not the part of Classes and object.
