Java: throw throws and Propagation
Answer
Use custom exceptions for domain-specific errors to improve clarity.
Creating custom exceptions helps encapsulate specific error conditions related to your application's domain, offering clarity and control over exception handling. They should extend 'Exception' for checked or 'RuntimeException' for unchecked exceptions. For instance, 'PaymentFailedException' in a payment system provides more information than a generic exception.
