The example is good. but to make it more apparent with the definition put the public Pet getPet(String petType) in an interface and let PetFactory inplement this interface. Reason any conventional definition tell you that there are four aspects to Factory Method.

1. Product — in your case it is Pet. The interface of objects created by the factory

2. Concrete Product — in your case it is Dog and Duck .The implementing class of Product. Object of this class is created by ConcreteCreator.

3. Creator — Which is the interface i am talking about. This interface defines the factory methods

4. Concrete Creator — PetFactory in your case. This class that extends Creator and that provides an implementation for the factoryMethod. This can return any object that implements Product interface.

This will give the readers exact implementation for Factory Method.
