Java is an OOP language but not a pure Object Oriented
Programming Language.

There are six qualities to make a programming language to
be pure Object Oriented. They are:

i)Encapsulation/Data Hiding
ii)Inheritance
iii)Polymorphism
iv)All predifined types are objects
v)All operations are performed by sending messages to
objects
and vi)All user defined types are objects.

Primitive data types, such as int, char, boolean are not
Objects,which are used by Java.It's why Java is not a "pure
object oriented programming language".
