How is Java a ‘pure OOP language’?
Java is purely an object oriented language due to the absence of global scope, Everything in java is an object, all the program codes and data resides within classes and objects. It comes with an extensive set of classes, arranged in packages, object model in java in sample and easy to extend.
Is Java a pure OOP language or not?
Java is not a pure OOP language due to two reasons: The first reason is that the Object oriented programming language should only have objects whereas java contains 8 primitive data types like char, boolean, byte, short, int, long, float, double which are not objects. These primitive data types can be used without the use of any object.
