## Answers

### Answer by Arti Mishra

## "Object Oriented Programming Language"

Java is not 100% object –oriented programming language because **it support primitive datatypes likes- int, float, char, long, boolean, byte...... etc.** **Which are not objects.** So for this reason **Java is not pure object oriented programming language**. \
**Properties of Pure OOP's Language**

- There are some properties of Pure OOP’s based language.

1. Inheritance

2. Polymorphism

3. Abstraction

4. Encapsulation/Data Hiding
