Factory Pattern
The Factory 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 encapsulates object creation logic, promoting loose coupling by separating the instantiation process from the client code that uses the objects. This pattern is commonly used in software development to manage object creation complexity and enhance flexibility.
Developers should learn and use the Factory Pattern when they need to create objects without specifying the exact class of object that will be created, such as in scenarios involving multiple product types, dynamic object creation based on runtime conditions, or when adding new product types without modifying existing client code. It is particularly useful in frameworks, libraries, and applications where object creation logic is complex or likely to change, such as in GUI toolkits, database connection management, or plugin systems.
