It addresses the same problems as the Simple Factory Pattern i.e. violation of Open/Closed Principle and the client having to be aware of all the concrete classes.Abstract Factory patterns work around a super-factory which creates other factories. Abstract factory pattern implementation provides us with a framework that allows us to create objects that follow a general pattern. So at runtime, the abstract factory is coupled with any desired concrete factory which can create objects of the desired type.In the previous chapter, we covered the first two creational patterns, the factory method and abstract factory, which both offer approaches to improve the way w Browse Library Advanced Search
