The purpose of Optional is to help design better APIs in which — just by reading the signature of a method — users can tell whether to expect an optional value. In addition, Optional forces you to actively unwrap an Optional to deal with the absence of a value; as a result, you protect your code against unintended null pointer exceptions.
