exchange java_java中用Exchange
展开全部
我推测你是说多线程中的Exchange
下面是一个例子：
比如生活中两个32313133353236313431303231363533e78988e69d8331333337613134人，一个人有零食，另一个人有钱，他们两个想等价交换，对好口号在某个地方相见，一个人先到了之后，必须等另一个人带着需要的东西来了之后，才能开始hi交换。import java.util.concurrent.Exchanger;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
public class ExchangeTest {
public static void main(String[] args) {
ExecutorService service = Executors.newCachedThreadPool();
final Exchanger exchanger = new Exchanger();
service.execute(new Runnable() {
@Override
public void run() {
try {
String data1 = "零食";
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) {
e.printStackTrace();
}
}
});
service.execute(new Runnable() {
@Override
public void run() {
try {
String data1 = "钱";
System.out.println("线程" + Thread.currentThread().getName()
+ "正在把数据 " + data1 + " 交换出去");
Thread.sleep((long) (Math.random() * 10000));
String data2 = (String) exchanger.exchange(data1);
System.out.println("线程 " + Thread.currentThread().getName()
+ "交换回来的数据是: " + data2);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}
