Advanced Java CompletableFuture Features: Two Stage Completion Methods (Part 2)

This video highlights the acceptEither() method, which triggers when one of two CompletableFuture objects completes, making it an "OR-style" operation. This method is used to process results without returning a value, employing a Consumer action, and facilitates parallel execution, as shown by running quicksort and mergesort simultaneously without worrying about which is faster. Results are handled by whichever algorithm finishes first, showcasing an application that prioritizes runtime efficiency. The method doesn't cancel the non-completing CompletableFuture, and for longer tasks, acceptEitherAsync() is recommended to offload work to a background thread, ensuring responsive applications.
