Sof Dev - Design Patterns

A creational design pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects that will be created.

Design Patterns are meant to provide a general reusable solution to one type of problem during software development.

Product Interface: Declares the interface for the product created by the factory. Concrete Products: The actual objects that implement the product interface. Creator Class: Declares the factory method that returns an instance of the product interface. It may also contain additional business logic. Concrete Creator Subclasses: Implement the factory method to create specific instances of the concrete products, thus defining the type of objects the factory will produce.

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.

Abstract Factory Interface: Declares the interface for creating product objects. Concrete Factories: Implement the Abstract Factory interface to produce families of related products. Abstract Product Interface: Declares the interface for a type of product object. Concrete Products: Implement the Abstract Product interface, representing specific product variants. Client: Uses the Abstract Factory and Abstract Product interfaces to interact with families of related products without being aware of their concrete classes.

While the Factory Pattern uses inheritance and gives a complete object in one go, the Abstract Factory Pattern uses composition and returns a family of related classes.
