Now going into the point the fact that a programming language is object oriented when there's a concept of classes and objects only,but In java there are primitive data types such as int,float etc.So java don't follow this rule properly and hence it's an object oriented language but not a pure object oriented language.

No, Java is an object oriented programming language but not purely a object oriented language. int, long, bool, float, char, etc as Objects: Smalltalk is a “pure” object-oriented programming language unlike Java and C++ as there is no difference between values which are objects and values which are primitive types. 3) Java is not pure object oriented programming language just because of primitive data types like byte, short, int, char, float, double, long, boolean etc. Why non-static variable cannot be referenced from a static method in Java. @Unknown, there are many things in Java which are not as per object oriented programming concept e.g. They are: 1. They are: Encapsulation/Data Hiding. are not classes. Consider: String s = string2.trim (); First, since "String" is immutable, the above code reeks of functional programming. They are: Encapsulation/Data Hiding. All predefined types are objects 6. Hi @Tom and @Reynier silverio, this question is mainly for purist, but some interviewer do prefer to ask, why Java is not a pure object oriented language or which language is considered as purest object oriented language etc. Java is about 99% Object oriented programming (OOP) language. is it very important whether java is a pure OO language? Someone said Java is a hybrid, which, IMO, is an accurate description. reply me aon bhaskarbhatt000@gmail.com. Actually, the way to go for a programming language is to mix various programming paradigms. I think so Tom! All user-defined types are objects. code. Experience.

I'm not sure what you mean by "their needs." An example of an object-oriented language that is not pure is C++. Abstraction 5. Please let me know in comments what you think—is Java is a purely Object Oriented Language or not? glad you liked it David, thx for your comment. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. etc, to be used, which are not objects. Abstraction 5. instead of int, float etc. It's just FORTRAN with lower case syntax. and that's what really matter. So primitives will be converted to Objects. i think this is the key point.
