“create” method of factory takes a parameter which tells it what kind of object has to be returned. Abstract factory pattern is almost similar to factory pattern and is considered to have a extra layer of abstraction over factory pattern. Then it will create a bunch of red roses. In the factory pattern, we create an object without exposing the creation logic to the client and refer to newly created objects using a common interface.
