java8 check optional null value more then once

Question

How do i write this in java8 in 1 line?

if (Optional.ofNullable(mapOfIntAndListOfObjects.get(spn)).isPresent()) {
    Date paydate = Optional.ofNullable(mapOfIntAndListOfObjects.get(spn).stream().findFirst()).get().orElse(new MyObject()).getPayDate();
    logger.info("paydate {} ", paydate);
    return paydate;
} 
return null;

Answer 1

Something like

Date payDate =  mapOfIntAndListOfObjects.getOrDefault(spn, Collections.emptyList())
        .stream()
        .findFirst()
        .orElse(new MyObject())
        .getPayDate();
logger.info("paydate {} ", paydate);
return payDate;

You don't really seem to be in need of wrapping them around Optional .

Answer 2

Try this:

return Optional.ofNullable(mapOfIntAndListOfObjects.getOrDefault(spn))
  .map(List::stream)
  .map(Stream::findFirst)
  .map(MyObject::getPayDate)
  .orElse(null); // or whatever default to return in case nothing found

Entirely uses the Optional functionality as intended. ie no default lists/values needed anywhere (except for the choice of what to return when nothing found).
