Enhancements in Java 21 for Concurrency — A Leap Toward Simplicity with Virtual Threads
๐งต Enhancements in Java 21 for Concurrency — A Leap Toward Simplicity with Virtual Threads ๐ Related Reads: Enhancements in Java 5 for Concurrency Enhancements in Java 8 for Concurrency Java has evolved significantly over the last two decades—from manual thread management in Java 5, to asynchronous computation via CompletableFuture in Java 8, and now, in Java 21 , a major shift with Virtual Threads under Project Loom. Let’s explore how Java 21 revolutionizes concurrency by making it simpler and more scalable without requiring complicated constructs. ๐ What Are Virtual Threads? Virtual Threads are lightweight, OS-independent threads managed by the JVM rather than the operating system. Unlike traditional (platform) threads, millions of virtual threads can run concurrently with minimal memory and scheduling overhead. ๐ Evolution at a Glance Feature Java 5 Java 8 Java 21 Task Management Executors, Thread pools CompletableFuture Virtual Threa...
