2020-4-5 · The Factory method is a creational design pattern that provides an interface for creating objects without specifying their concrete classes.

2020-11-19 · The factory method is one of the most used and one of the more robust design patterns. There are only few points which have to be considered when you implement a factory method. When you design an application just think if you really need it a factory to create objects. Maybe using it will bring unnecessary complexity in your application.
2018-5-31 · Factory Method Pattern vs. Simple Factory Pattern Simple factory is just an encapsulation of a piece of code so that it can be reused. It provides only one way of creating objects and hence if you want to create objects in other ways you have to modify the factory itself but which is the strength of factory method pattern.
