Why is Java not a pure OOP Language?

Answer 1

Java is a OOP language and it is not a pure Object Based Programming Language.

Many languages are Object Oriented. There are seven qualities to be satisfied for a programming language to be pure Object Oriented. They are:

1. Encapsulation/Data Hiding
2. Inheritance
3. Polymorphism
4. Abstraction
5. All predefined types are objects
6. All operations are performed by sending messages to objects
7. All user defined types are objects.

Java is not because it supports Primitive datatype such as int, byte, long... etc, to be used, which are not objects.

Contrast with a pure OOP language like Smalltalk, where there are no primitive types, and boolean, int and methods are all objects.

Answer 2

Java is, in fact, not typically considered a pure objected oriented language. In a pure OO language, every data item would be an object, which is not true in Java. The "primitive" types of Java (byte, short, int, long, float, double, boolean, char) are not actually objects. Note that they can be "wrapped" in objects of the same name (there exists an Integer class, for example).

Answer 3

No. Java is an object oriented programming language but it is not 100% purely object oriented. It still has some features related to other programming patterns and hence cannot be considered pure object oriented.

Answer 4

C++ is not a pure OOP language because it supports the concept of primitives, such as int, char and bool, as well as pointer variables. A pure OOP language has none of these: all so-called "primitives" are actually implemented as objects, each with associated member methods, such as int::AsString(). C++ primitives have no associated methods whatsoever.

Answer 5

Java is called as OOP since it allows u to create an object of a particular type and then use that object for your further use

Answer 6

java is not purely oops because of primitive types in java like int and float double

Answer 7

Yes, it is pure OOP.
