How do I handle exceptions in futures in my code?

How do I handle exceptions in futures in my code?

You can handle exceptions in futures by using the exceptionally method or by wrapping your future in a try-catch block.

Can you give me an example of using the exceptionally method?

Sure! Here's a simple example: future.exceptionally(ex -> { System.out.println(ex.getMessage()); return null; }); This will print the exception message if it occurs.

What if I want to handle multiple exceptions?

You can use a combination of handle and exceptionally to manage multiple exceptions. The handle method allows you to process both the result and the exception.

Thanks! Is there a way to retry the future if it fails?

Yes, you can implement a retry mechanism by using a loop or recursion to re-invoke the future upon failure.
