Object Oriented Programming

I am disagree with you , C# is more object oriented than Java, and both of them are not pure object oriented, i think a language can never be pure object oriented , it is not possible.

A fully object-oriented language needs to have

all the 4 oops concepts.
all predefined and,
user-defined types must be objects and,
all the operations should be performed only by calling the methods of a class.

But both java and C#

has predefined primitive data types (which are not objects ex structs etc).
You can access the members of a static class without creating an object of it.
