Java: Timeouts and Retries

Use exceptionally() to handle exceptions. Frame the concept in practical terms so you can explain it during interview discussion.

When working with CompletableFuture, it's important to handle exceptions like HttpTimeoutException to avoid unexpected application behavior. You can use the exceptionally() method to provide a fallback logic. For instance, when making parallel API calls for product details, if one call fails due to timeout, you can log the error or provide a default response.
