本文介绍了一个基于Java实现的多线程售票系统的具体代码。该系统通过实现Runnable接口完成多线程操作，并使用同步机制确保并发情况下票数正确递减。文章展示了如何通过创建多个线程模拟不同售票点同时进行售票的过程。

package day;

public class Mytd implements Runnable {         //通过实现Runnable接口来实现多线程
    private int ticketcount = 100;
    Object ob = new Object();                  //加锁
    private int m = 100;

    public Mytd(int t) {                       //有参构造方法
        this.ticketcount = t;
        this.m = t;
    }

    public Mytd() {                           //无参构造方法

    }

    public void sellticket() {                //卖票方法
       synchronized (ob) {                    //同步线程锁
            if (ticketcount > 0) {
                ticketcount--;
                int num = this.m - ticketcount;
                System.out.println(Thread.currentThread().getName()
                        + "卖出第" + num + "张票，还剩" + ticketcount + "张票");
            } else {
                System.out.println("票已经卖完");
                return;
            }
       }
    }

    @Override
    public void run() {
        while (ticketcount > 0) {
            sellticket();
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        }
    }
}

package day;

public class Work {
    public static void main(String[] args) {
        Mytd run = new Mytd(100);
        Thread th1 = new Thread(run,"东风路售票点");           //开启五个线程
        Thread th2 = new Thread(run,"吉祥路售票点");
        Thread th3 = new Thread(run,"从动路售票点");
        Thread th4 = new Thread(run,"文明路售票点");
        Thread th5 = new Thread(run,"好听路售票点");
        th1.start();
        th2.start();
        th3.start();
        th4.start();
        th5.start();
    }
}
