Better way for using builder pattern with optional values?

Question

We are using the builder pattern to create some input for service, and it looks like something like this (simplified):

final SomeInput input = SomeInput.builder()
    .withSomeId(....) 
    .withSomeState(....)
    ...
    .build();

There's some attribute that we want to set in SomeInput, but only if it is present. So after creating the object, I do something like this:

Optional<String> secondaryId = infoProvider.getSecondaryId();
if (secondaryId.isPresent()) {
   input.setSecondaryId(secondaryId.get());
}

I was wondering:

a) Is there a better/cleaner way to do this? b) If I do need to do it this way, can I avoid the "if" statement and utilize some functionality with Optional?

(Note: I cannot change the builder itself, and I cannot that the secondaryId is a String, but that what we retrieve from infoProvider is an optional)

Answer 1

A little bit cleaner would be to use ifPresent

secondaryId.ifPresent(input::setSecondaryId);

but that's pretty much the best you can get with these requirements.
