The Factory Pattern defines an interface for creating objects, but it allows subclasses or other parts of the code to decide which class to instantiate. Instead of directly creating instances, the pattern delegates the creation of objects to a factory method. 🏗️
This pattern helps to encapsulate the object creation process, promoting flexibility and making it easier to **swap ** object types or extend functionality without modifying the code that uses them.
- Factory Method → Defines the method responsible for creating objects.
- Product → Represents the objects created by the factory.
- Concrete Factory → Implements the factory method to instantiate specific product classes.
✅ When the object creation process is complex or requires various configurations.
✅ When you want to decouple the client code from the object creation logic.
✅ When you need to create families of related objects or have variations in product types.
- Vehicle Production: A factory that produces different types of vehicles (cars, trucks, bikes) based on the input. 🚗
- UI Elements: A factory that creates different UI components like buttons, text boxes, or sliders depending on the platform. 🖥️
- Database Connections: A factory that provides database connection objects depending on the type of database ( MySQL, PostgreSQL, etc.). 🗄️
