Abstract factory pattern we can consider as another layer of abstraction over factory pattern. Abstract Factory defines an interface for creating all distinct products but leaves the actual product creation to concrete factory classes. The getFactory method is then : public AnimalFactory getFactory(String choice) { return map.get(choice); } As a consequence, adding a new type of Animal does not require to modify anything, just create the Animal and AnimalFactory implementations, register the factory.Of course, there are other implementations of the getFactory method, for example Toolkit.getToolkit() which is a singleton. All we need to do to extend this code is add an abstract class.To be able to use it in the proper place, it is imperative that one understands its use. I’ve updated the article.IMHO, this is the Factory Method pattern. I think Abstract Factory usually relies on a two steps use : AnimalFactory factory = xxx.getFactory(animalType); Animal animal = factory.getAnimal(); The getFactoryMethod can be a static method, an instance method; it returns an implementation of AnimalFactory (the implementation is a “concrete” factory). This adds to the abstraction quotient of the factory pattern.
