> Note that "Long" in Java can be null because it is boxed, "long" (lowercase) however cannot be null, but it also can't be Optional<long>. Java sucks :) I think using primitive types as generics is something that makes Java less ergonomic than C# (where they’re called unmanaged types), whether it is considered justified or necessary. To say Java sucks because of this is a bit much. To say Java sucks because you can’t avoid null is definitely warranted. (You can say good things about Java, and not being able to opt out of nulls is not one of them.)
