实验一多线程同步处理java.docVIP

实验一：多线程同步处理 实现内容：编写一多线程程序，实现对某一银行帐户的存取款操作。 要求：多个用户均可操作该帐户，存款随意存，取款要求帐户的余额足够才能取（不能透支）。每一项存取款操作均要互斥进行。 参考资料：/62575/27069 前半部分代码： 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; /** * Java线程：条件变量 * * @author leizhimin 2009-11-5 10:57:29 */ 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, 14100); 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(); } } /** * 存款线程类 */ class SaveThread extends Thread { private String name; //操作人 private MyCount myCount; //账户 private int x; //存款金额 SaveThread(String name, MyCount myCount, int x) { = name; this.myCount = myCount; this.x = x; } public void run() { System.out.println(name+存款操作+x); myCount.saving(x, name); } } /** * 取款线程类 */ class DrawThread extends Thread { private String name; /
