Creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. Antipatterns describe common mistakes, errors, and people issues that can cause a software project to fail. Creational patterns allow objects to be created in a system without having to identify a specific class type in the code, so you do not have to write large, complex code to instantiate an object. And, to make our work even harder, we also happen to be denied access to the object which needs to handle the event.
