How can I implement asynchronous code in Java?

You can use the CompletableFuture class in Java to handle asynchronous programming. Would you like a code example?

Yes, please provide a simple example.

Sure! Here's a basic example:

import java.util.concurrent.CompletableFuture;

public class AsyncExample {
    public static void main(String[] args) {
        CompletableFuture<Void> future = CompletableFuture.runAsync(() -> {
            System.out.println("Running in async mode!");
        });
        future.join(); // Wait for the async task to complete
    }
}

This code runs a task asynchronously. Do you have any questions about it?

What if I want to handle exceptions in the async task?

You can use the exceptionally method to handle exceptions. Here's how:

CompletableFuture<Void> future = CompletableFuture.runAsync(() -> {
    throw new RuntimeException("Error occurred!");
}).exceptionally(ex -> {
    System.out.println("Exception: " + ex.getMessage());
    return null;
});
future.join();

This will catch and handle any exceptions thrown in the async task.
