1. When would you create a custom checked exception versus a custom unchecked exception?
Difficulty: EasyType: SubjectiveTopic: Exceptions
Create a checked exception to force callers to acknowledge a recoverable domain error—like a business rule violation or a missing required configuration. Create an unchecked exception when the failure indicates a programmer mistake or an unexpected state that typical callers cannot handle—like illegal arguments, null misuses, or invariant violations. Use descriptive names and include context in the message.
