How to print even and odd numbers using Completable Future and Executor services

Today, Xiaobian will share with you how to print even and odd knowledge points using Completable Future and Executor services. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Next, we will use Java 8 Completable Future and Executor services to achieve this.

We created two single-threaded executors and assigned them a name.

Using IntStream, we iterate from 1 to 101.

Use two completable future to check for odd or even numbers, and call join after the call so that the completable future completes its execution.

Finally, shut down the executor service.

Import java.util.concurrent.CompletableFuture;import java.util.concurrent.ExecutorService;import java.util.concurrent.Executors;import java.util.stream.IntStream;public class Solution {public static void main (String [] args) {ExecutorService firstExecutorService = Executors.newSingleThreadExecutor (r-> {Thread t = new Thread (r); t.setName ("first"); return t }); ExecutorService secondExecutorService = Executors.newSingleThreadExecutor (r-> {Thread t = new Thread (r); t.setName ("second"); return t;}) IntStream.range (1101) .forEach (num-> {CompletableFuture thenApplyAsync = CompletableFuture.completedFuture (num) .thenApplyAsync (x-> {if (x% 2 = = 1) {System.out.println (x + "+ Thread.currentThread (). GetName () } return num;}, firstExecutorService); thenApplyAsync.join () CompletableFuture thenApplyAsync2 = CompletableFuture.completedFuture (num) .thenApplyAsync (x-> {if (x% 2 = = 0) {System.out.println (x + "" + Thread.currentThread () .Async () } return num;}, secondExecutorService); thenApplyAsync2.join ();}); firstExecutorService.shutdown (); secondExecutorService.shutdown () }} that's all about the article "how to print even and Odd numbers using Completable Future and Executor Services".
