Abstract factory design pattern medium. Abstract factory patterns work around a super factory which creates other factories. The abstract factory design pattern solves problems like. Abstract factory pattern is almost similar to factory pattern is considered as another layer of abstraction over factory pattern. Abstract factory design pattern is an easy way of getting rid of boiler plate code.
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 is a super factory which will return the best factory based on the input. Abstract factory patterns work around a super factory which creates other factories. The basic structure of an abstract factory design pattern is given by.
It provides an interface for creating families of related or dependent objects without specifying their concrete classes. The abstract factory is useful in a situation that requires the creation of many different types of objects all derived from a common base type.

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. Object creation has been abstracted and there is no need for hard coded class names in the client code. The abstract factory design pattern is one of the twenty three well known gof design patterns that describe how to solve recurring design problems to design flexible and reusable object oriented software that is objects that are easier to implement change test and reuse. Concrete products are various implementations of abstract products grouped by variants.
The abstract factory defines a method for creating the objects which subclasses can then override to specify the derived type that will be created. Abstract factory design pattern is one of the creational pattern. Abstract products declare interfaces for a set of distinct but related products which make up a product family. It falls under the creational design pattern.
This structural code demonstrates the abstract factory pattern creating parallel hierarchies of objects. The abstract factory interface declares a set of methods for creating each of the abstract products. Example of abstract factory design pattern.
