Java 实现异步方法：利用 CompletableFuture 示例

```java import java.util.concurrent.CompletableFuture; public class AsyncDemo { public static void main(String[] args) { asyncMethod().thenAccept(result -> System.out.println("异步方法执行结果： " + result)); System.out.println("主线程继续执行"); } public static CompletableFuture<String> asyncMethod() { return CompletableFuture.supplyAsync(() -> { try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } return "Hello, World!"; }); } } ``` ######[AI写代码神器 | 165点数解答 | 2024-05-24 16:21:52]
