认识达内从这里开始

昆明IT培训的小编这一期给大家分享线程的工具类（Exchange）。

public class Exchanger<V>extends Object

可以在对中对元素进行配对和交换的线程的同步点。每个线程将条目上的某个方法呈现给exchange方法，与伙伴线程进行匹配，并且在返回时接收其伙伴的对象。Exchanger可能被视为SynchronousQueue的双向形式。Exchanger可能在应用程序（比如遗传算法和管道设计）中很有用。

实例：

import java.util.concurrent.Exchanger;

import java.util.concurrent.ExecutorService;

import java.util.concurrent.Executors;

/**

*线程间的交换数据

*/

public class ExchagerTest {

public static void main(String[] args) {

ExecutorService service = Executors.newCachedThreadPool();

Exchanger<String> exchange = new Exchanger<String>();

service.execute(new MyThread<String>("爱情", exchange, "爱情"));

service.execute(new MyThread<String>("关晓彤", exchange, "关晓彤"));

service.shutdown();

}

static class MyThread<T> extends Thread {

private T data;

private Exchanger<T> exchange;

public MyThread(T data, Exchanger<T> exchange, String name) {

this.data = data;

this.exchange = exchange;

setName(name);

}

@Override

public void run() {

System.out.println(getName() + "正准备把" + data + "交换出去");

try {

Thread.sleep((int) (Math.random() * 10000));

T datas = exchange.exchange(data);

System.out.println(getName() + "换回的为：" + datas);

} catch (Exception e) {

e.printStackTrace();

}

}

}

}
