Abstract Factory Design Java

Abstract factory design pattern video tutorial.

Abstract factory design java. A class delegates object creation to a factory object instead of creating objects directly. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. Abstract factory pattern is almost similar to factory pattern is considered as another layer of abstraction over factory pattern. Here s the animal interface.

In factory pattern we create object without exposing the creation logic to the client and refer to newly created object using a common interface. Factory pattern is one of the most used design patterns in java. Abstract factory pattern is yet another creational design pattern and is considered as another layer of abstraction over factory pattern in this tutorial we will expand the scope of car factory problem discussed in factory pattern we will learn when to use factory pattern by expanding scope of car factory and then how abstract factory pattern solves the expanded scope. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object.

Abstract factory patterns work around a super factory which creates other factories. Public interface animal string getanimal. After that we ll manage access to them using an abstract factory abstractfactory. In the video i discuss when and how to implement an abstract factory pattern.

In this example we ll create two implementations of the factory method design pattern. That is define an interface abstractfactory for creating objects and implement the interface. Abstract factory is a creational design pattern which solves the problem of creating entire product families without specifying their concrete classes. This factory is also called as factory of factories.

First we ll create a family of animal class and will later on use it in our abstract factory. So this is the reason that abstract factory pattern is one level higher than the factory pattern. Design start out using factory method less complicated more customizable subclasses proliferate and evolve toward abstract factory prototype or builder more flexible more complex as the designer discovers where more flexibility is needed. The abstract factory design pattern describes how to solve such problems.

Abstract factory pattern says that just define an interface or abstract class for creating families of related or dependent objects but without specifying their concrete sub classes that means abstract factory lets a class returns a factory of classes. Abstract factory pattern. Abstract factory design pattern is one of the creational pattern. Abstract factory patterns work around a super factory which creates other factories.

Abstract factory pattern in java. Encapsulate object creation in a separate factory object.
