In object oriented programming, objects provide a layer which can be used to separate internal from external code and implement abstraction and encapsulation. External code can only use an object by calling a specific instance method with a certain set of input parameters, reading an instance variable, or writing to an instance variable.
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. [32] New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for ...
This comparison of programming languages compares how object-oriented programming languages such as C++, Java, Smalltalk, Object Pascal, Perl, Python, and others manipulate data structures. Object construction and destruction
Designed with secure computing in mind, accomplished chiefly by strict adherence to the object-oriented computing model. eC: 2004: Jérôme Jacovella-St-Louis (Ecere) A super-set of C adding object-oriented features (inspired by C++), properties, dynamic modules and reflection developed as part of the Ecere SDK project, an open-source cross ...

In the programming language Dylan, which is an object-oriented language that supports multimethods and doesn't have a concept of this, sending a message to an object is still kept in the syntax. The two forms below work in the same way; the differences are just syntactic sugar .
In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages , but generally the shared aspects consist of state ( variables ) and behavior ( methods ) that are each either associated with a particular object or with all objects of that class.
