Answer
Unhandled exceptions can lead to application failures.
CompletableFuture provides asynchronous execution benefits but can lead to application failures if exceptions are not properly handled. Without handling exceptions, errors in any part of the computation chain can remain unnoticed, causing unexpected application behavior. For example, while performing multiple API calls concurrently, each CompletableFuture should have a mechanism to handle exceptions, such as using exceptionally() to manage potential failures.
