The point of the new Optional type in Java isn't to prevent NPEs, it's to make using the new Streams API cleaner. Since you can now flow through optional values in a stream you can ignore whether the stream contains optionals or not and only deal with them at the end. It's certainly possible that in a future version of Java the optional type might be paired with something like pattern matching to prevent NPEs with some syntax sugar, but that's not the reason that the Optional type exists today.
