Maintainability:?

Q: Maintainability:?

Short answer: Since object creation is centralized in the factory classes, it is easier to manage and update how objects are instantiated. If the creation logic changes (e.g., adding configuration parameters), it only needs to be updated in the factory class. Real-Time Use Case Examples: Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
