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:
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.
C is a procedure oriented language ,Where C++ & java are object oriented language.But java is platform independent.So generally C is called POP.C++ is called OOP.But java is OOP , which is platform independent.If java does not support primitive data type then it is called as pure object oriented language.
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.
An OOP language is an object oriented programming language. The plural is therefore OOP languages, not oops language. A pure OOP language is one that does not have the concept of a primitive data type. That is, a data type that has no member methods whatsoever. In pure OOP languages, all primitive data types (pointers, characters, integers, floating point and array types) are implemented as objects that are associated with a default constructor, copy and move constructors, conversion constructors, copy and move assignment operators, type conversion operators and a destructor, all of which are members of the object's class.
OOP stands for Object Oriented Programming. Everything in Java is an Object. Any class you create extends the Object class by default thereby making everything in Java an object. Moreover, you can use features like Inheritance, Polymorphism, Encapsulation etc which are OOP concepts thereby making Java an Object Oriented Programming Language
No. Java is 100% OOP while C++ supports the concept of primitives (which it inherited from C). Thus C++ supports far more features than Java, but it does not support any more OOP features than Java. Note that there are only four primary OOP features: encapsulation, abstraction, inheritance and polymorphism. Anything beyond that is implementation-specific and outwith the scope of OOP.
Java is renouned as one of the most classic OOP engines. OOP or object oriented programming reduces all functions to various tasks of objects. A heirarcy of classes of objects all inherit the knowledge and aptitude of class they "extend". Eventually, every object can be traced back to the class "Object". Java is known as a very common language, with a structure that can be a good starting point to jump to almost any language.
Object-oriented programming (OOP) is not a separate language, it is a programming principal. C++ is a programming language that supports OOP as well as procedural programming and is backwardly compatible with C, the main language from which it evolved. The OOP aspect constitutes the bulk of C++ to the extent that if you're programming in C++ then you're using OOP. If you were to actively avoid using OOP entirely then you'd be writing C-style, in which case you'd be better off using C itself since C has no OOP capability whatsoever. C++ is not 100% OOP like Java or C#, but that is not a weakness of the language. OOP is merely a programming tool and, like any other tool, you use it wherever it is appropriate to do so, just as you use C-style wherever appropriate. C++ is nothing if not flexible.
