Abstract Factory Design Pattern Javatpoint

Public interface animal string getanimal.

Abstract factory design pattern javatpoint. So this is the reason that abstract factory pattern is one level higher than the factory pattern. This structural code demonstrates the abstract factory pattern creating parallel hierarchies of objects. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. A factory pattern or factory method pattern says that just define an interface or abstract class for creating an object but let the subclasses decide which class to instantiate.

Factory method pattern exposes a method to the client for creating the object whereas in the case of abstract factory they expose a family of related objects which may consist of these. This factory is also called as factory of factories. Here s the animal interface. Abstract factory pattern is almost similar to factory pattern is considered as another layer of abstraction over factory pattern.

First we ll create a family of animal class and will later on use it in our abstract factory. Abstract factory pattern. In other words subclasses are responsible to create the instance of the class. Abstract factory design pattern is one of the creational pattern.

After that we ll manage access to them using an abstract factory abstractfactory. Abstract factory patterns work around a super factory which creates other factories. Abstract factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes. Factory method is used to create one product only but abstract factory is about creating families of related or dependent products.

Abstract factory patterns work around a super factory which creates other factories. Difference between abstractfactory and factory design patterns are as follows. Structural code in c. In this example we ll create two implementations of the factory method design pattern.
