How to convert Optional<Object> to Optional [closed]

Answer 1

Use:

String value = Optional.ofNullable(getObjectOrNullIfNotAvailable()).map(Object::toString).orElse(null);

Otherwise, you can check if an Object is null and return in that case a String with "null" inside with String.valueOf(Object obj) or Objects.toString(Object obj). Eg.

  String value = Objects.toString(getObjectOrNullIfNotAvailable())
