jdk string thread class

 俩个线程之间交换数据之后继续运行，除了全局静态变量，jdk5提供了Exchanger类来解决这个问题。不多说，直接上例子

 package com.skydream.thread.exchanger;

 import java.util.concurrent.Exchanger;

 public class ExchangerTest {

     /**
      * @param args
      * @throws InterruptedException
      */
     public static void main(String[] args) throws InterruptedException {
            final Exchanger objExchanger = new Exchanger();
            new Thread(){
                public void run() {
                    System.out.println("子线程正在运行");
                    try {
                     Thread.sleep(5000);
                     String strData = objExchanger.exchange("skydream");
                     System.out.println("交换后的数据"+strData);
                 } catch (InterruptedException e) {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
                 }
                };
            }.start();
            System.out.println("子线程已经启动");
            String strChildThreadData = objExchanger.exchange("main data");
            System.out.println("主线程交换后的数据 "+strChildThreadData);
     }

 }
