Makes code more difficult to read as all of your code is behind an abstraction that may in turn hide abstractions. Account. A - This type of design pattern comes under creational pattern. It’s similar to the factory and can contain many factories in it, we can design many factories and relations with the design pattern in java. Are you among this group of people or are you highly skilled? Modify the Toy class: Let’s modify the NyCar and NyHelicopter classes to implement the prepare() method. If Creator is an interface or abstract class then it overrides the factory method to return an instance of a ConcreteProduct. Let’s complete the code for NyToysFactory: Now, each franchise will have their components supplied by a component factory, which is controlled by Dragon Inc. HQ. These are also the most confusing patterns for developers who are new to the world of designing. Read more. This pattern is the best one to solve some problems with factory and abstract factory design patterns when objects contain many attributions. Factory Method Design Pattern in C# with Real-time Example. In this pattern an interface is responsible for creating a factory of related objects without explicitly specifying their classes.
