Can you provide some examples of using ExecutorService in Java?

Sure! The ExecutorService is a high-level API for managing threads in Java. One common example is using it to run tasks asynchronously.

How do I create a fixed thread pool using ExecutorService?

You can create a fixed thread pool by using Executors.newFixedThreadPool(int nThreads). For example: ExecutorService executor = Executors.newFixedThreadPool(3);

What about submitting tasks to the ExecutorService?

You can submit tasks using the submit() method. For instance: Future<ResultType> future = executor.submit(() -> { /* task code */ });

You should call executor.shutdown() to stop accepting new tasks and finish existing ones. You can also use shutdownNow() to attempt to stop all actively executing tasks.
