Detailed explanation-1: -Factory Method is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

Detailed explanation-2: -Factory Method is a creational design pattern used to create concrete implementations of a common interface. It separates the process of creating an object from the code that depends on the interface of the object. For example, an application requires an object with a specific interface to perform its tasks.

Detailed explanation-3: -The factory design pattern is used when we have a superclass with multiple sub-classes and based on input, we need to return one of the sub-class. This pattern takes out the responsibility of the instantiation of a class from the client program to the factory class.

Detailed explanation-4: -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.
