What are some examples of using ExecutorService in Java?

Can you give me some examples of using ExecutorService in Java?

Sure! The ExecutorService in Java is used to manage a pool of threads. One common example is using it to execute 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). This will create a pool with a fixed number of threads.

Can you show me a code snippet for that?

Absolutely! Here's a simple example:

ExecutorService executor = Executors.newFixedThreadPool(3);
executor.submit(() -> {
    // Your task here
});
executor.shutdown();

What happens if I submit more tasks than the number of threads?

If you submit more tasks than the available threads, the extra tasks will wait in a queue until a thread becomes available.
