Factory Pattern

Updated 06 Sep 2026

•
What it is
- •
  a creational pattern that separates the logic of creating an object from the client code that uses it, so the client never depends directly on a concrete class
•
Problem it solves
- •
  without it: if (type.equals("cheese")) pizza = new CheesePizza(); — the client must be edited every time a new type is added
- •
  with it: Pizza pizza = pizzaFactory.createPizza("cheese"); — the client delegates creation entirely to the factory
•
Benefits
- •
  loose coupling (client doesn't depend on concrete implementations), open for extension (new types added without touching client code), testability (creation can be mocked), reusability
•
Structure
- •
  an AbstractFactory defines the interface every concrete factory must implement, each producing a family of related products * related
