What are the patterns of factory?

Specifically, using factories provides encapsulation, and means the code is not tied to specific classes or objects , and thus the class hierarchy or prototypes can be changed or refactored without needing to change code that uses them – they abstract from the class hierarchy or prototypes.

Abstract Factory patterns work around a super-factory which creates other factories. This factory is also called as factory of factories. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object.

The Factory Method pattern, sometimes referred to as the Virtual Constructor pattern, provides a way to conceal an object’s creation logic from client code, but the object returned is guaranteed to adhere to a known interface .19 Nis 2021

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 . In other words, subclasses are responsible to create the instance of the class.
