2. Template method pattern - Wikipedia

   en.wikipedia.org/wiki/Template_method_pattern

   In object-oriented programming, the template method is one of the behavioral design patterns identified by Gamma et al. [1] in the book Design Patterns. The template method is a method in a superclass, usually an abstract superclass, and defines the skeleton of an operation in terms of a number of high-level steps. These steps are themselves ...

3. Object-oriented programming - Wikipedia

   en.wikipedia.org/wiki/Object-oriented_programming

   Object-oriented programming uses objects, but not all of the associated techniques and structures are supported directly in languages that claim to support OOP. The features listed below are common among languages considered to be strongly class- and object-oriented (or multi-paradigm with OOP support), with notable exceptions mentioned.

4. Design Patterns - Wikipedia

   en.wikipedia.org/wiki/Design_Patterns

   Chapter 1 is a discussion of object-oriented design techniques, based on the authors' experience, which they believe would lead to good object-oriented software design, including: "Program to an interface, not an implementation." (Gang of Four 1995:18) Composition over inheritance: "Favor 'object composition' over 'class inheritance'." (Gang of ...

5. Class-based programming - Wikipedia

   en.wikipedia.org/wiki/Class-based_programming

   An object must be explicitly created based on a class and an object thus created is considered to be an instance of that class. An object is similar to a structure, with the addition of method pointers, member access control, and an implicit data member which locates instances of the class (i.e., objects of the class) in the class hierarchy ...

6. Decorator pattern - Wikipedia

   en.wikipedia.org/wiki/Decorator_pattern

   The decorator [4] design pattern is one of the twenty-three well-known design patterns; these describe how to solve recurring design problems and design flexible and reusable object-oriented software—that is, objects which are easier to implement, change, test, and reuse.

7. Class (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Class_(computer_programming)

   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.

8. Inheritance (object-oriented programming) - Wikipedia

   en.wikipedia.org/wiki/Inheritance_(object...

   Many object-oriented programming languages permit a class or object to replace the implementation of an aspect—typically a behavior—that it has inherited. This process is called overriding. Overriding introduces a complication: which version of the behavior does an instance of the inherited class use—the one that is part of its own class ...

9. Creational pattern - Wikipedia

   en.wikipedia.org/wiki/Creational_pattern

   In other words, they create independency for objects and classes. Consider applying creational patterns when: A system should be independent of how its objects and products are created. A set of related objects is designed to be used together. Hiding the implementations of a class library or product, revealing only their interfaces.
