Answer
CompletableFuture allows async task chaining with thenApply, thenAccept, thenCombine, exceptionally.
Enables building non-blocking, reactive pipelines.
Enables building non-blocking, reactive pipelines.
Quick Answer
CompletableFuture chaining: thenApply(fn) transforms result synchronously. thenApplyAsync(fn) transforms in another thread. thenCompose(fn) chains another CompletableFuture (flatMap). thenCombine(other, fn) combines two futures' results when both complete. thenAccept(consumer) consumes without returning. Build complex async pipelines: fetch data -> transform -> combine -> handle errors -> deliver result.
