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.

But in terms of the wiring up of the classes it is pretty close to what you will see in real world code. This finishes the tutorial on Factory Method Pattern. A closely related pattern is Abstract Factory Pattern.
An increasingly popular definition of factory method is a static method of a class that returns an object of that class type. But unlike a constructor the actual object it returns might be an instance of a subclass. Unlike a constructor an existing object might be reused instead of a new object created.
