Factory Method Design Pattern Explained Simple Factory vs Factory Method in Java Geekific

The Factory Method is one of the most powerful creational design patterns, but before we understand it, we first need to look at the Simple Factory idiom. In this video, we break down both approaches using a fun real-world example of a burger restaurant and its delivery app. We’ll see how relying on a simple factory helps centralize object creation, and then understand why the Factory Method pattern goes one step further by using inheritance to fully decouple creation from usage.
What you’ll learn:
Simple Factory Idiom: Centralizing object creation in one place
Factory Method Pattern: Delegating product creation to subclasses
UML Breakdown: How clients, creators, and products interact
Open/Closed Principle in action: Extending menus without breaking existing code
Why Factory Method is better suited when products grow in complexity
By the end, you’ll clearly understand when to use a simple factory versus when to rely on the factory method, and how both help us write more flexible, maintainable, and scalable software that follows SOLID principles. Perfect for interviews, project design, or just leveling up your OOP skills.
