Advanced Java Completable Future Features: Arbitrary-Arity Methods

This video explores the advanced features of Java's completable futures framework, specifically its allOf() and anyOf() arbitrary-arity methods that handle multiple CompletableFuture objedts simultaneously. These methods enhance reactive programming by allowing bulk operations on a set of CompletableFuture objects, triggering completion stages upon their collective completion. I illustrate these methods with a modern Java example where large and random BigFraction objects are reduced and multiplied using the Java completable futures framework in the common fork-join pool, demonstrating the use of the allOf() method to "wait" for all tasks to complete and the anyOf() method to "wait" for just one. This approach significantly boosts responsiveness by preventing the calling thread from blocking, making code more efficient and reactive.
