Object Oriented Languages

The language have to support several of the OOP's 
(Object Oriented Programming)features to claim that
they are object oriented. Depending on the features 
they support,they are classified into the following
categories.

A) Object Based Programming Languages (OBPL):-

Object based programming is the style of programming 
that primarily supports data Encapsulation. Major 
features supports by Object Based Programming Languages 
are:-

( i ) Data Encapsulation and Object Identity.

(ii)  Data Hiding and access Mechanisms.

(iii) Operator Overloading.

(iv)  Automatic initialization and clean-up of objects.

Languages that support programming with objects are said
to be OBPL is ADA

B) Object Oriented Programming Language (OOPL):

Object Oriented Programming Language supports all of 
ObjectBase Programming features, and additionally the 
following:

(i)  Inheritance     (ii) Dynamic Binding

Object Oriented Programming Language are further classified 
as-
(a) Pure Object Oriented Languages :

Object Oriented Language whose development had been object 
right from the beginning
eg.  Simula, Smalltalk, Eiffel, Java

(b) Extented Object Oriented Language:

Object Oriented Languages are those languages which initially
existed as procedural language and were enhances in capabilities
to support Object Oriented features.

eg. C++, Objective 'C', Object Pascal
