java多线程之通过Exchanger线程间传递数据

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
