Why java is not considered as a full object oriented programming language while comparing with c#?

Question

Object oriented programming

Answer 1

Java supports for primitive data types.Primitive types are not objects ,therefore Java is not considered as full object oriented programming language

Answer 2

C# is  fully OOP because everything are objects. C# does not differentiate between primitive types and objecttypes like in Java. Hence, int is an object, not a primitive type. Second, it's not purely OOP because it has features that rightly belong to procedural languages such as function pointers.

Answer 3

pointer is not available in java and function is also present in c#
