I get it. Functional code is still kind of considered the "new hotness" in languages like Java, but THAT DOESN'T MEAN YOU NEED TO CRAM IT IN EVERYWHERE FOR THE SAKE OF IT. If in doubt, *please* go for the simpler, classic option...

Just inherited a code base that's full of things like this:

Optional.of(getResult()).filter(s -> s.equals(true)).ifPresent(s -> callService());
Optional.of(getResult()).filter(s -> s.equals(false)).ifPresent(s -> logError());
