What are async methods in Java?

Async methods in Java allow for non-blocking operations, enabling better performance in concurrent programming.

Can you give me an example of how to implement an async method?

Sure! You can use the CompletableFuture class to create async methods. Here's a simple 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
    }
}

What are the benefits of using async methods?

The benefits include improved responsiveness, better resource utilization, and the ability to handle multiple tasks simultaneously.

Are there any drawbacks to using async methods?

Yes, potential drawbacks include increased complexity in error handling and debugging, as well as the risk of callback hell.
