IMO, Your current example above is Factory Method.
As you have defined an interface (Factory) with a factory method (create) that allows sub classes (FactoryA and FactoryB) to decide which class to instantiate (Product derived classes).
Вопрос
The main difference between a "factory method" and an "abstract factory" is that the factory method is a single method, and an abstract factory is an object. But, sometimes I can't say what it is,for example
class Product{
}
interface Facotory{
public Product create();
}
class FactoryA implements Facotory{
public Product create() {
return null;
}
}
class FactoryB implements Facotory{
public Product create() {
return null;
}
}
Can you tell me it is factory method or abstract factory?Thank you!
