What are the benefits of using factory patterns in software design?

Factory patterns provide a way to create objects without specifying the exact class of the object that will be created. This promotes loose coupling and enhances code maintainability.

Can you explain how it improves code maintainability?

By using factory patterns, you can change the implementation of the object creation process without altering the code that uses the objects. This means you can easily swap out implementations or add new ones.

Are there any performance implications of using factory patterns?

Generally, factory patterns may introduce a slight overhead due to the additional layer of abstraction, but the benefits in maintainability and flexibility often outweigh this cost.

Can you give an example of a factory pattern in action?

Sure! For instance, in a game, you might have a CharacterFactory that creates different types of characters like Warrior, Mage, or Archer based on input parameters, allowing for easy expansion.
