Understanding the Factory Design Pattern
The Factory Design Pattern is a creational pattern that provides a way to create objects without specifying the exact class of the object that will be created. It defines an interface for creating an object, but allows subclasses to alter the type of objects that will be created. Components of the Factory Design Pattern: Product: The interface or abstract class that defines the type of object to be created. ConcreteProduct: Implements the Product interface and defines the specific object to be created. Creator: The interface or abstract class that declares the factory method for creating Product objects. ConcreteCreator: Implements the Creator interface and overrides the factory method to return an instance of ConcreteProduct. Simple Example: Let’s create a simple example where we have a Vehicle interface, and concrete implementations like Car and Bike. We will use a factory to create instances of these vehicles. ...
