What is factory and Abstract Factory design pattern?

Factory Method pattern is responsible for creating products that belong to one family, while Abstract Factory pattern deals with multiple families of products. Factory Method uses interfaces and abstract classes to decouple the client from the generator class and the resulting products.

What is difference between Abstract Factory and factory method design patterns?

The main difference between a “factory method” and an “abstract factory” is that the factory method is a single method, and an abstract factory is an object. The Factory Method pattern uses inheritance and relies on a subclass to handle the desired object instantiation.

Is Abstract Factory a design pattern?

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.

What is used in abstract factory pattern?

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.

Why to use factory pattern?

The main reason for which the factory pattern is used is that it introduces a separation between the application and a family of classes (it introduces weak coupling instead

What is factory method?

Factory method is a creational design pattern which solves the problem of creating product objects without specifying their concrete classes.

What is an abstract factory?

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.

What is a factory class?

Factory classes provide an interface for creating families of related objects. Factory classes are useful when the decision of which class to use must be done at run time and cannot be hard coded during development. Factory classes encapsulate the logic needed to decide which subclass to instantiate…
