How do I handle exceptions in a thread pool?

To handle exceptions in a thread pool, you can use a custom ThreadFactory to catch exceptions and log them.

Can you give me an example of a custom ThreadFactory?

Sure! Here's a simple example:

public class CustomThreadFactory implements ThreadFactory {
    @Override
    public Thread newThread(Runnable r) {
        return new Thread(r) {
            @Override
            public void run() {
                try {
                    super.run();
                } catch (Exception e) {
                    System.err.println("Exception in thread: " + e.getMessage());
                }
            }
        };
    }
}

What about using an ExecutorService?

You can wrap your tasks in a Callable and handle exceptions in the Future returned by the ExecutorService. Check the result with future.get().

Is there a way to handle multiple exceptions?

Yes, you can aggregate exceptions in a collection and handle them after all tasks are completed.
