How do I handle exceptions in asynchronous Java code?

In asynchronous Java, you can handle exceptions using CompletableFuture's exceptionally() method or try-catch blocks.

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

Sure! Here's a simple example:

CompletableFuture.supplyAsync(() -> {
    // some code that might throw an exception
})
.exceptionally(ex -> {
    System.out.println("Exception: " + ex.getMessage());
    return null;
});

What if I want to handle multiple exceptions?

You can chain multiple exceptionally() calls or use a custom exception handler to manage different exceptions.

Is there a way to recover from an exception in async operations?

Yes, you can use the handle() method, which allows you to process the result or handle the exception in one place.
