How do I handle exceptions in Java asynchronous programming?

In Java, you can handle exceptions in asynchronous programming using CompletableFuture. You can use the exceptionally method to handle exceptions.

Can you give me an example of using CompletableFuture with 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 methods or use handle method, which allows you to process both the result and the exception.

Can you explain the difference between exceptionally and handle?

Certainly! The exceptionally method only handles exceptions, while handle can process both the result and the exception, allowing for more flexibility.
