Java多线程实现简单的售票程序

设计一个多线程程序如下：设计一个火车售票模拟程序。假如火车站要有100张火车票要卖出，现在有5个售票点同时售票，用5个线程模拟这5个售票点的售票情况

1、要求打印出每个售票点所卖出的票号

2、各售票点不能售出相同票号的火车票

import java.util.Random;


public class SaleTicket implements Runnable {

    public int total;

    public int count;

    public SaleTicket() {

       total = 100;

        count = 0;

    }



    public void run() {

        while (total > 0) {

            synchronized (this) {

                if(total > 0) {
                    try {

                        //Thread.sleep(800);

                        Thread.sleep(new Random().nextInt(1000));

                    } catch (InterruptedException e) {

                        e.printStackTrace();

                    }

                    count++;
                    total--;

                    System.out.println(Thread.currentThread().getName() + "\t当前票号：" + count);

                }

            }

        }

    }


    public static void main(String[] args) {

        SaleTicket st = new SaleTicket();

        for(int i=1; i<=5; i++) {

            new Thread(st, "售票点" + i).start();

        }

    }

}
