How do I use the Java Executors framework?

The Java Executors framework simplifies concurrent programming. You can create a thread pool using Executors.newFixedThreadPool(). Would you like an example?

Yes, please provide an example of creating a thread pool.

Sure! Here's a simple example:

ExecutorService executor = Executors.newFixedThreadPool(3);
executor.submit(() -> {
    System.out.println("Task 1");
});
executor.submit(() -> {
    System.out.println("Task 2");
});
executor.shutdown();

This creates a pool of 3 threads and submits two tasks.

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

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