How can I handle errors in asynchronous Java code?

In asynchronous Java, you can handle errors using try-catch blocks within your async methods or by using CompletableFutures.

Can you give me an example of using CompletableFuture for error handling?

Sure! You can use the exceptionally method to handle exceptions. For example:

CompletableFuture.supplyAsync(() -> {
    // some code that might throw an exception
})
.exceptionally(ex -> {
    // handle the exception
    return null;
});

What about using the Future interface? Is it different?

Yes, with the Future interface, you can check if the task is done and handle exceptions using the get() method, which throws ExecutionException.

Are there any best practices for error handling in async Java?

Yes, some best practices include logging errors, using specific exception types, and ensuring that your async methods are well-documented.
