In object-oriented programming, an interface or protocol type [a] is a data type that acts as an abstraction of a class.It describes a set of method signatures, the implementations of which may be provided by multiple classes that are otherwise not necessarily related to each other. [1]
In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns , which describe how to solve recurring problems in object-oriented software. [ 1 ]
A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message.An object consists of state data and behavior; these compose an interface, which specifies how the object may be used.
The book was written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, with a foreword by Grady Booch. The book is divided into two parts, with the first two chapters exploring the capabilities and pitfalls of object-oriented programming, and the remaining chapters describing 23 classic software design patterns.
During the late 1970s and 1980s, object-oriented programming rose to prominence. The Flavors object-oriented Lisp was developed starting 1979, introducing multiple inheritance and mixins. [15] In 1981, Goldberg edited the August issue of Byte Magazine, introducing Smalltalk and object-oriented programming to a wide audience. [16]
