  2. Encapsulation (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Encapsulation_(computer...

    Encapsulation is a technique that encourages decoupling. All object-oriented programming (OOP) systems support encapsulation, [2] [3] but encapsulation is not unique to OOP. Implementations of abstract data types, modules, and libraries also offer encapsulation.

  3. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    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.

  4. Separation of concerns - Wikipedia

    en.wikipedia.org/wiki/Separation_of_concerns

    The mechanisms for modular or object-oriented programming that are provided by a programming language are mechanisms that allow developers to provide SoC. [4] For example, object-oriented programming languages such as C#, C++, Delphi, and Java can separate concerns into objects, and architectural design patterns like MVC or MVP can separate presentation and the data-processing (model) from ...

  5. Abstraction (computer science) - Wikipedia

    en.wikipedia.org/wiki/Abstraction_(computer_science)

    Various object-oriented programming languages offer similar facilities for abstraction, all to support a general strategy of polymorphism in object-oriented programming, which includes the substitution of one data type for another in the same or similar role.

  6. Information hiding - Wikipedia

    en.wikipedia.org/wiki/Information_hiding

    In object-oriented programming, information hiding (by way of nesting of types) reduces software development risk by shifting the code's dependency on an uncertain implementation (design decision) onto a well-defined interface. Clients of the interface perform operations purely through the interface, so, if the implementation changes, the ...

    en.wikipedia.org/wiki/Comparison_of_programming...

    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

  8. Composition over inheritance - Wikipedia

    en.wikipedia.org/wiki/Composition_over_inheritance

    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. [2]

  9. Object model - Wikipedia

    en.wikipedia.org/wiki/Object_model

    Examples are the object models of Java, the Component Object Model (COM), or Object-Modeling Technique (OMT). Such object models are usually defined using concepts such as class, generic function, message, inheritance, polymorphism, and encapsulation.
