java多线程之通过Exchanger线程间传递数据

来源：互联网发布：詹姆斯赛季数据编辑：程序博客网时间：2024/06/12 14:47

public class ExchangerTest {public static void main(String[] args) {ExecutorService service = Executors.newCachedThreadPool();final Exchanger exchanger = new Exchanger();service.execute(new Runnable(){public void run() {try {String data1 = "zxx";System.out.println("线程" + Thread.currentThread().getName() + "正在把数据" + data1 +"换出去");Thread.sleep((long)(Math.random()*10000));String data2 = (String)exchanger.exchange(data1);System.out.println("线程" + Thread.currentThread().getName() + "换回的数据为" + data2);}catch(Exception e){}}});service.execute(new Runnable(){public void run() {try {String data1 = "lhm";System.out.println("线程" + Thread.currentThread().getName() + "正在把数据" + data1 +"换出去");Thread.sleep((long)(Math.random()*10000));String data2 = (String)exchanger.exchange(data1);System.out.println("线程" + Thread.currentThread().getName() + "换回的数据为" + data2);}catch(Exception e){}}});}}

运行结果如下：

线程pool-1-thread-1正在把数据zxx换出去
线程pool-1-thread-2正在把数据lhm换出去
线程pool-1-thread-1换回的数据为lhm
线程pool-1-thread-2换回的数据为zxx
