JAVA多线程模拟生产者与消费者_实例

用两个线程模拟存票、售票过程
假定开始售票处并没有票，一个线程往里存票，另外一个线程则往出卖票

public class ThreadTest {public static void main(String[] args) {Tickets t=new Tickets(20);new Producer(t).start();new Consumer(t).start();}static class Tickets{int size;//总数int num=0;//号码Boolean available=false;public Tickets(int size){this.size=size;}public synchronized void put(){if(available==true)try {wait();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}System.out.println("Producer puts ticket "+(++num));available=true;notify();}public synchronized void get(){if(available==false)try {wait();} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}System.out.println("Consumer get ticket "+(num));available=false;notify(); if (num==size) num=size+1 ; }}static class Producer extends Thread{Tickets t=null;public Producer(Tickets t){this.t=t;}public void run(){while(t.num<t.size){t.put();}}}static class Consumer extends Thread{Tickets t=null;public Consumer(Tickets t){this.t=t;}public void run(){while(t.num<t.size){t.get();}}}}

 

有什么问题，希望大家提出来共同讨论
