Answer
Higher-level catches provide centralized handling, while lower-level catches offer specific recovery.
Catching exceptions at higher layers, like the application entry point, simplifies error management but can obscure the context. Conversely, lower-level catches (closer to where the error occurs) allow for more precise recovery, like retry logic in database operations. For example, catching database access exceptions at a service layer might allow for retries, while catching them at the controller level might only allow logging and user notification.
