Java: Checked vs Unchecked Exceptions
Answer
Unchecked exceptions are not part of the method signature, affecting API reliability.
Unchecked exceptions do not need to be declared in a method's signature, which can lead to less predictable APIs. Users of the API might not be aware of potential exceptions unless they are documented. For instance, a NullPointerException could occur if an API method doesn’t document that it requires non-null arguments, leading to runtime errors.
