多线程和并发库应用十六-Exchanger

本文主要是介绍多线程和并发库应用十六-Exchanger，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

用于线程之间的数据交换，线程完成一定的数据后项目其他线程进行数据交换。第一个先拿出数据等到第二个线程执行完成后进行数据交换。

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){}               }   });     }
}
