In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...
A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander [ 1 ] and has been adapted for various other disciplines, particularly software engineering .
The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes.

Framework - hide complex code behind a simple interface; Facade pattern: create a simplified interface of an existing interface to ease usage for common tasks; Flyweight pattern: a large quantity of objects share a common properties object to save space; Marker pattern: an empty interface to associate metadata with ...
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. [1] It is often used to make existing classes work with others without modifying their source code.
