What role does the ExecutorService interface play in managing task execution in Java?

The ExecutorService interface in Java plays a key role in managing the execution of asynchronous tasks. It abstracts the creation and management of threads, allowing tasks to be run without directly creating and controlling threads.

Main features of ExecutorService:

• Managing a thread pool for efficient resource utilization.
• Running Runnable or Callable tasks with the ability to obtain results via Future.
• Conveniently shutting down task execution and properly stopping the service.

Example usage:

ExecutorService executor = Executors.newFixedThreadPool(3);
executor.submit(() -> {
    System.out.println("Executing task in a separate thread");
});
executor.shutdown();

Thus, ExecutorService simplifies parallel programming, enhancing scalability and manageability of multithreaded applications.
