此博客展示了Java中两线程之间数据交换的代码示例。通过使用`Exchanger`类和线程池，创建两个线程，每个线程准备数据并尝试与对方交换，最后输出换回的数据，体现了Java多线程数据交互的实现。

import java.util.concurrent.Exchanger;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
/*
* 两线程之间数据的交换

public class ExchangerDemo {
public static void main(String[] args) {
ExecutorService service= Executors.newCachedThreadPool();
final Exchanger exchanger = new Exchanger();
service.execute(new Runnable() {
public void run() {
String data1="zz";
try {
System.out.println("线程"+Thread.currentThread().getName()+"准备把"+data1+"换取出");
Thread.sleep((long)Math.random()*1000);
String data2 = (String) exchanger.exchange(data1);
System.out.println("线程"+Thread.currentThread().getName()+"换回的数据为"+data2);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});

service.execute(new Runnable() {
public void run() {
String data1="xx";
try {
System.out.println("线程"+Thread.currentThread().getName()+"准备把"+data1+"换取出");
Thread.sleep((long)Math.random()*1000);
String data2 = (String) exchanger.exchange(data1);
System.out.println("线程"+Thread.currentThread().getName()+"换回的数据为"+data2);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});
}
