Toot

Written by Rachel Greenham on 2025-01-04 at 13:43

here's a #java style question.

// completed with null if not found

CompletableFuture findObject();

// completed exceptionally if not found

CompletableFuture findObject();

// empty Optional if not found

CompletableFuture<Optional> findObject();

they'd all work so this is about style. which would be preferred?

the middle one is odd-one-out as it semantically says it's an error if the object can't be found rather than that being allowable.
