Factory Method Pattern
The Factory Method Pattern 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. It defines a method that should be used for creating objects instead of calling a constructor directly, promoting loose coupling by delegating instantiation logic to subclasses. This pattern is widely used in object-oriented programming to encapsulate object creation and enhance code flexibility and maintainability.
Developers should use the Factory Method Pattern when they need to create objects without specifying the exact class of the object that will be created, such as in frameworks or libraries where the client code should be decoupled from concrete implementations. It is particularly useful in scenarios where a class cannot anticipate the class of objects it must create, like in GUI toolkits, plugin architectures, or when adding new product types without modifying existing code. This pattern helps in adhering to the Open/Closed Principle by allowing extension without modification.
