java await signal_Java中的await()/signal()用法

二、方法await()/signal()

在JDK5.0以后,JAVA提供了新的更加健壮的线程处理机制,包括了同步、锁定、线程池等等,可以实现更小粒度上的控制。await()和signal()就是其中用来同步的两种方法,功能基本上和wait()/notify()相同,完全可以取代它们,但是它们和新引入的锁定机制Lock直接挂钩,具有更大的灵活性。

import java.util.LinkedList;

import java.util.concurrent.locks.*;

public class Sycn2

{

private LinkedList myList = new LinkedList();

private int MAX = 10;

private final Lock lock = new ReentrantLock();

private final Condition full = lock.newCondition();

private final Condition empty = lock.newCondition();

public void start()

{

new Thread(new Producer())。start();

new Thread(new Consumer())。start();

}

public static void main(String[] args) throws Exception

{

Sycn2 s2 = new Sycn2();

s2.start();

}

class Producer implements Runnable

{

public void run()

{

while (true)

{

lock.lock();

try

{
