多线程中的生产者和消费者.doc

多线程中的生产者和消费者一、文件结构 二、各个类的作用、和源代码。 Bread.java自定义一个面包类ducerconsumer;public class Bread int id; public Bread(int i) this.id=i; Override public String toString() return Bread id= + id + ; Basket.java定义一个篮子类，用于存放面包(Bread对象)ducerconsumer;public class Basket int index=0; Bread breadBasket=new Bread12;/定义一个数组存放面包 public synchronized void push(Bread bread) while(this.index=breadBasket.length)/思考为什么不用if try this.wait(); catch(InterruptedException e) e.printStackTrace(); this.notifyAll();/唤醒等待的线程 breadBasketthis.index=bread; this.index+; public synchronized Breadpop() try Thread.sleep(1000); catch (InterruptedExceptione) e.printStackTrace(); while(this.index=0) /思考为什么不用if try this.wait(); catch(InterruptedException e) e.printStackTrace(); this.notifyAll();/唤醒等待的线程 this.index-; return breadBasketthis.index; Producer.java生产者ducerconsumer;public class Producer implements Runnable Basket breadBasket=null; public Producer(Basketbasket) this.breadBasket=basket; Override public void run() for(int i=0;i20;i+) Bread bread=new Bread(i); this.breadBasket.push(bread); System.out.println(生产者：+Thread.currentThread().getName()+生产+bread); Consumer.java消费者ducerconsumer;public class Consumer implements Runnable Basket breadBasket=null; public Consumer(Basketbasket) this.breadBasket=basket; Override public void run() for(int i=0;i20;i+) Breadbread=this.breadBasket.pop(); System.out.println(消费者:+Thread.currentThread().getName()+消费+bread); Test.java测试类ducerconsumer;public class Test public static void main(Stringargs) Basketbasket=new Basket(); Consumerconsumer1=new Consumer(basket); Consumerconsumer2=new Consumer(basket); Producerproducer1=new Producer(basket); Producerproducer2=new Producer(basket); Thread t3=new Thread(producer1); Thread t4=new Thread(producer2); Thread t1=new T
