: The classic Gang of Four (GoF) pattern where subclasses decide which class to instantiate by overriding a method.
: Specific implementations of the product interface.
For more technical implementation details, you can refer to comprehensive guides like Refactoring.Guru or Microsoft Learn's overview of factory patterns . The Factory Pattern — A Simple Guide | by Isaac Cummings
: Ideal for when object construction involves complex logic or multiple steps. Real-World Example Imagine a Logistics App : Interface : Transport (with a method deliver() ). Concrete Products : Truck and Ship . Factory : Logistics class.
: RoadLogistics (returns a Truck ) and SeaLogistics (returns a Ship ).
: Object creation logic is centralized in one place rather than scattered throughout your app.
: The client code relies on an interface rather than specific classes, making the system easier to modify.
: You can introduce new product types without breaking existing client code.
