What are the best practices for handling exceptions in asynchronous Java code?

When handling exceptions in asynchronous Java, it's important to use try-catch blocks within your async methods. You should also consider using CompletableFuture's exceptionally() method to handle exceptions gracefully.

Can you explain how CompletableFuture's exceptionally() method works?

Sure! The exceptionally() method allows you to define a fallback action if the CompletableFuture completes exceptionally. It takes a function that receives the Throwable and returns a new value.

What about using the async/await pattern in Java?

Java doesn't have a built-in async/await pattern like JavaScript, but you can achieve similar behavior using CompletableFuture and lambda expressions.

Are there any common pitfalls to avoid?

Yes, common pitfalls include not handling exceptions properly, blocking the main thread, and not chaining CompletableFutures correctly.
