This post revisits Java 8's CompletionStage API and specifically its implementation in the standard Java library, CompletableFuture. The API is explained by examples that illustrate the various behaviors, where each example focuses on a specific one or t
Java has seen a major shift towards functional programming paradigms. One of the features introduced in Java 8 is CompletableFuture, which provides a flexible way to work with asynchronous computations. CompletableFuture allows developers to chain and combine multiple asynchronous tasks in a more concis...
