生产者-消费者简单实现

一、车间

/**
 * 车间(电商平台)
 * @author superman
 *
 */
public class Tmall {

    private int count;        //当前货物数量
    public  final int max=10; //车间最大的存储数量

    public  synchronized void produce() {
        while(count>=max) {
             try {
                System.out.println(Thread.currentThread().getName()+":"+"库存数量达到上限,生产停止");
                wait();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        count++;
        System.out.println(Thread.currentThread().getName()+":"+"生产者生产,"+"当前库存的数量为"+count);
        notifyAll();

    }


    public  synchronized void consume() {
        while(count<=0) {
            try {
                System.out.println(Thread.currentThread().getName()+":"+"库存数量为0,停止消费");
                wait();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        count--;
        System.out.println(Thread.currentThread().getName()+":"+"消费者消费,当前库存为"+count);
        notifyAll();
    }



}

二、生产者

/***
 * 生产者
 * @author superman
 *
 */
public class Producer implements Runnable {
     private Tmall tmall;

    public  Producer(Tmall tmall) {

        this.tmall=tmall;
    }

    @Override
    public void run() {
        // TODO Auto-generated method stub
        while(true) {
            tmall.produce();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

    }
}

三、消费者

/**
 * 消费者
 * @author superman
 *
 */
public class Consumer  implements Runnable{

    private Tmall tmall; 

    public Consumer(Tmall tmall) {
        this.tmall=tmall;

    }
    @Override
    public void run() {
         while(true) {
            tmall.consume();
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
         }  
    }
}

四、主调用类

/**
 * 主函数实现生产者，消费者模拟过程
 * @author superman
 *
 */
public class Main {

    public static void main(String[] args) {
        Tmall mall=new Tmall();          //车间
        Producer p=new Producer(mall);   //生产者
        Consumer c=new Consumer(mall);   //消费者
        new Thread(p).start();
        new Thread(p).start();
        new Thread(p).start();
        new Thread(p).start();
        new Thread(p).start();

        new Thread(c).start();
        new Thread(c).start();
        new Thread(c).start();
        new Thread(c).start();
    }
}
