Guide to ExecutorService vs. CompletableFuture

Date: 2024-05-29

Java's ExecutorService and CompletableFuture are key tools for handling concurrent tasks. ExecutorService manages a thread pool, efficiently executing submitted tasks. CompletableFuture, introduced in Java 8, focuses on asynchronous computation results, offering methods for chaining tasks, handling exceptions, and managing timeouts. While ExecutorService manages the execution, CompletableFuture manages the result of asynchronous operations, providing a richer API for complex scenarios. They often complement each other for robust concurrency management.
