Optional vs if/else-if performance java 8

Question

Hello i have two samples of code

if/else if/else statements

private Object getObj(message) {
        if (message         


        

Answer 1

There is a third form (allowing still some variation).

return Stream.>of(message::getA, message::getB, message::getC)
        .map(Supplier::get)
        .filter(Objects::nonNull)
        .findFirst()
        .orElse(null);

Probably the least flexible and efficient at this moment, but clear.
