The factory design pattern is used when we have a superclass with multiple sub-classes and based on input, we need to return one of the sub-class.
It is a creational design pattern which talks about the creation of an object. introduces loose coupling between classes which is the most important principle one should consider and apply while designing the application architecture This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object.In Factory pattern, we create object without exposing the creation logic to the client and refer to newly created object using a common interface.Create concrete classes implementing the same interface.Create a Factory to generate object of concrete class based on given information.Use the Factory to get object of concrete class by passing an information such as type. In short, we are trying to achieve Pseudo polymorphism by letting the subclass to decide what to create, and so this Factory method is also called as.Note- Above interface could be created as an abstract class as well.Now let’s use factory class to create and get an object of concrete class by passing some information.If you like GeeksforGeeks and would like to contribute, you can also write an article using.Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below.Please write to us at contribute@geeksforgeeks.org to report any issue with the above content.We use cookies to ensure you have the best browsing experience on our website. Factory design pattern is used to create objects or Class in Java and it provides loose coupling and high cohesion. It is a creational design pattern which talks about the creation of an object. This pattern takes out the responsibility of the instantiation of a class from the client program to the factory class.
Experience. Create concrete classes implementing the same interface. public class Rectangle … If we notice the name,In Java constructors are not polymorphic, but by allowing subclass to create an object, we are adding polymorphic behavior to the instantiation. acknowledge that you have read and understood our,GATE CS Original Papers and Official Keys,ISRO CS Original Papers and Official Keys,ISRO CS Syllabus for Scientist/Engineer Exam,Best Practices of Object Oriented Programming (OOP),Difference Between Architectural Style, Architectural Patterns and Design Patterns,Generate a string of size N whose each substring of size M has exactly K distinct characters,Polling and Streaming - Concept & Scenarios,Difference between Good Design and Bad Design in Software Engineering,Java Program to Print a Square Pattern for given integer,Java Program for Naive algorithm for Pattern Searching,Java Program for KMP Algorithm for Pattern Searching,Java Program for Rabin-Karp Algorithm for Pattern Searching,Analysis and Design of Combinational and Sequential circuits,An Introduction to Software Development Design Principles,Program to print numbers with diamond pattern,Program to print modified Binary triangle pattern,Java 8 | Consumer Interface in Java with Examples,Java 8 | BiConsumer Interface in Java with Examples,Deleting a User in Linux using Python Script.Must Do Coding Questions for Companies like Amazon, Microsoft, Adobe, ...Top 10 Programming Languages to Learn in 2020 - Demand, Jobs, Career Growth,Modulo Operator (%) in C/C++ with Examples,Get Your Dream Job With Amazon SDE Test Series.How To Convert Python Dictionary To JSON?Find the duration of difference between two dates in Java,How to remove all non-alphanumeric characters from a string in Java,How to check if string contains only digits in Java,How to create a COVID-19 Tracker Android App,Write Interview
