Virtual threads are lightweight Java threads designed to make high-concurrency blocking workloads easier to express.

try (var executor = Executors.newVirtualThreadPerTaskExecutor()) {
    Future<String> future =
        executor.submit(() -> fetchRemoteData());
    System.out.println(future.get());
}

Virtual threads do not make CPU-bound work faster. They improve scalability for workloads where many tasks spend time waiting. Concurrency still needs limits around databases, APIs, queues, and other external resources.
