Why java is called purely object oriented language?

Answer 1

Java is called a "pure" object-oriented language because it requires that all code written in it be wrapped in objects.

This differs from the more common meaning of "pure" object-oriented (everything is an object) in that Java has primitive types and primitive operations on them - int, char, double, float, long and addition, subtraction, multiplication, division. A real example of a PURE object-oriented language is Smalltalk, one of Java's predecessors.

Answer 2

No. C++ fully supports all object-oriented principals, but retains the notion of primitive data types such as int and char, as well as pointers, which are strictly non-object oriented. To be a pure object oriented language, like C# or Java, all data types must be implemented as objects.

Answer 3

Java doesn't give you the choice -- it's object-oriented, period. C++ is object-oriented, but you can mix OOP with structured and procedural programming, as well as include Assembly Language routines.

Answer 4

C++ inherits from C which is non-object oriented. C++ code can mix object-oriented code with procedural and structured programming and even raw assembly instructions. Object-oriented programming is not a magic bullet to every problem, and was never intended as such. Due to its reliance on object-oriented programming, Java is not ideally suited to solving certain problems. Not to mention its level of abstraction and reliance on the virtual machine being detrimental to performance. C++ is better suited to solving more complex problems than Java and because it compiles to native machine code has none of the performance issues associated with Java.
