How has ExecutorService changed in recent Java versions?

The ExecutorService in Java has seen significant improvements in recent versions, particularly with the introduction of new factory methods and enhancements that simplify the process of task scheduling and concurrency management.

Starting with Java 8, the CompletableFuture class was introduced, providing a powerful way to handle asynchronous programming. The ExecutorService can now seamlessly work with CompletableFuture to optimize asynchronous workflows.

Java 9 further enhanced the ExecutorService by introducing the Executors factory methods such as newWorkStealingPool(), which creates a new thread pool that uses a work-stealing algorithm. This allows for improved efficiency and easier scaling of applications.

Moreover, Java 11 added enhancements to the ExecutorService with methods such as invokeAll() and invokeAny(), making it easier to handle collections of tasks in parallel.
