java代码

一个两个用户的案例，生产者和消费者，当仓库产品为0时，生产者生产产品，然后休眠，消费者进入消费完产品后唤醒生产者，生产者再生产产品，如此循环：

/** 消费者类*/public class Customer implements Runnable {    private Product pro;    public Customer(Product pro) {        this.pro = pro;    }    @Override    public void run() {        while (true) {            try {                Thread.sleep(500);            } catch (InterruptedException e1) {                // TODO Auto-generated catch block                e1.printStackTrace();            }            synchronized (pro) {                System.out.println("消费者抢到仓库");                if (pro.getNum() != 0) {                    System.out.println("消费");                    try {                        Thread.sleep(2000);                    } catch (InterruptedException e) {                        // TODO Auto-generated catch block                        e.printStackTrace();                    }                    pro.setNum(0);                    pro.notify();//唤醒在此对象监视器上等待的单个线程                }            }        }    }}/** 生产者类*/public class Productor implements Runnable {    private Product pro;    public Productor(Product pro) {        this.pro = pro;    }    @Override    public void run() {        while (true) {            synchronized (pro) {                System.out.println("生产者抢到仓库");                if (pro.getNum() == 0) {                    System.out.println("生产");                    try {                        Thread.sleep(3000);                    } catch (InterruptedException e) {                        // TODO Auto-generated catch block                        e.printStackTrace();                    }                    pro.setNum(1);                    try {                        pro.wait();// 在其他线程调用此对象的 notify() 方法或 notifyAll() 方法前，导致当前线程等待。                    } catch (InterruptedException e) {                        // TODO Auto-generated catch block                        e.printStackTrace();                    }                }            }        }    }}/**仓库类*/public class Product {    private int num ;    public int getNum() {        return num;    }    public void setNum(int num) {        this.num = num;    }}/**测试类*/public class Test {    public static void main(String[] args) {        Product product = new Product();        Thread productor = new Thread(new Productor(product));        Thread customer = new Thread(new Customer(product));        productor.start();        try {            Thread.sleep(500);        } catch (InterruptedException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        customer.start();    }}/*运行结果：生产者抢到仓库生产消费者抢到仓库消费生产者抢到仓库生产消费者抢到仓库消费*/……
