how to write code in java 8 use Optionals

Question

I have a code like this. How can it be rewritten more correctly?

Optional<String> getNameBySiiPriorityInfo(Optional<SiiPriorityInfo> siiPriorityInfo){
    return siiPriorityInfo.isPresent() ? Optional.ofNullable(siiPriorityInfo.get().getName()) : Optional.empty();
}

Answer 1

If you have an optional and you want to get another optional given by performing an operation on the object inside the optional, use map.

return siiPriorityInfo.map(SiiPriorityInfo::getName);
