I have an instance of OptionalLong. But one of my libraries requires an Optional as a parameter.

How can I convert my Option

    This should work.

    Optional returnValue = Optional.empty();
    if(secondScreenHeight.isPresent()) {
          returnValue = Optional.of(secondScreenHeight.getAsLong());
    }
