Client Code:?

Q: Client Code:?

Short answer: The client code does not need to know which logger is being used. It interacts with the factory (e.g., ConsoleLoggerFactory), which produces the desired logger. This decouples the client code from the concrete logging classes, promoting flexibility and scalability. Key Benefits of the Factory Method Pattern: 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.
