In Java 8, transform Optional of an empty String in Optional.empty

Question

Given a String I need to get an Optional, whereby if the String is null or empty the result would be Optional.empty. I can do it this way:

String ppo = \"\";
Opt         


        

Answer 1

How about:

Optional ostr = ppo == null || ppo.isEmpty()
    ? Optional.empty()
    : Optional.of(ppo);

You can put that in a utility method if you need it often, of course. I see no benefit in creating an Optional with an empty string, only to then ignore it.
