Java线程：新特征-条件变量（2）-优快云博客

本文通过一个Java示例程序介绍了如何使用条件变量来协调线程间的操作。该示例涉及一个银行账户的存款和取款场景，利用ReentrantLock和Condition确保线程安全。

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class Test {
        public static void main(String[] args) {
                //创建并发访问的账户
                MyCount myCount = new MyCount("95599200901215522", 10000);
                //创建一个线程池
                ExecutorService pool = Executors.newFixedThreadPool(2);
                Thread t1 = new SaveThread("张三", myCount, 2000);
                Thread t2 = new SaveThread("李四", myCount, 3600);
                Thread t3 = new DrawThread("王五", myCount, 2700);
                Thread t4 = new SaveThread("老张", myCount, 600);
                Thread t5 = new DrawThread("老牛", myCount, 1300);
                Thread t6 = new DrawThread("胖子", myCount, 800);
                //执行各个线程
                pool.execute(t1);
                pool.execute(t2);
                pool.execute(t3);
                pool.execute(t4);
                pool.execute(t5);
                pool.execute(t6);
                //关闭线程池
                pool.shutdown();
        }
