Is there any programming language which is completely object oriented?

Answer 1

Java and C++ are not completely object oriented. They both have primitive types (int, float, etc.) that are not objects. SmallTalk, on the other hand, is a fully object oriented language that has been around for some years, but mainly as a research language. In SmallTalk, ints and floats have methods. (actually, they receive "messages", but that's a quibble) So, the line:

42 factorial

sends the "factorial" message to the number 42, which responds with the appropriate answer. You can't quite do this in Java or C++. In those languages, you'd have to write a factorial method for some other class, and then send 42 as an argument. This is different.

There's some good wiki at the link below.

Answer 2

Object orientedness is primarily in how you think when you write code, not the language you choose to write it in. For example, a class in C++ like:

class Foo {
public:
void Bar();
...
};

is virtually the same as something like this in C:

struct Foo { ... };
void Bar(Foo* implicit_parameter);

Conversely, anybody can write a "blob" class in C++ or Java, consisting of all the program's methods and data members, then instantiate one instance of it [I have :-(], which isn't object oriented. The OOP is in sticking to the principles of modularisation and object self-responsibility.

Answer 3

"Object Oriented" is a design concept. Different languages have different ways of "enforcing" this concept.

Java and C# are the "most" object oriented languages I have experience with.

C++ is a blend of traditional "function based" capabilities with "object based" paradigms.

Answer 4

JAVA is a complete and purely OOP language.
while, C++ is partially OOP language.
VB is an Object Base application development tool
(VB is not a language & its not ObjectOriented but ObjectBase)

i dont lnow about other language..

Answer 5

JAVA, it is so far a very Object-Oriented programming language.
