先建立一个容器

/**
 * 容器
 * 共享资源
 * @author Administrator
 *
 */
public class SynStack {
    
    int index = 0;
    //容器
    SteamBread[] stb = new SteamBread[6];
    
    /**
     * 往容器中放产品
     */
    public synchronized void push(SteamBread st){
        while(index == stb.length){
            try {
                this.wait();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        notify();//唤醒正在等待的线程
        stb[index] = st;
        this.index++;
    }
    /**
     * 从容器中取产品
     */
    public synchronized SteamBread pop(){
        while(index == 0){
            try {
                this.wait();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        notify();
        this.index--;
        return stb[index];
    }

}

产馒头

package com.newer.cn;

public class Producer implements Runnable{
    SynStack ss = null;
    
    public Producer(SynStack ss) {
        // TODO Auto-generated constructor stub
        this.ss = ss;
    }
    @Override
    public void run() {
        //开始生产馒头
        for(int i = 1;i <= 20;i++){
            SteamBread stb = new SteamBread(i);
            System.out.print("生产了::::::");
            ss.push(stb);
            System.out.println("生产了"+stb);
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        
    }

}

消费馒头

package com.newer.cn;


public class Consume implements Runnable{
    SynStack ss = null;
    
     public Consume(SynStack ss) {
         this.ss = ss;
    }
    @Override
    public void run() {
        //开始消费馒头
        for(int i = 1;i <= 20;i++){
            System.out.print("消费了::::::");
            SteamBread stb = ss.pop();
            System.out.println("消费了"+stb);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        
    }

}

测试

package com.newer.cn;

public class Test2 {

    public static void main(String[] args) {
        SynStack ss = new SynStack();
        //生产者线程
        Producer p = new Producer(ss);
        Thread tp = new Thread(p);
        
        //消费者线程
        Consume c = new Consume(ss);
        Thread tc = new Thread(c);
        
        tp.start();
        tc.start();
    }

}
