Problem A: 实验十二：窗口卖票

Problem Description

1.实验目的
(1) 掌握线程的创建、使用及sleep方法的运用

2.实验内容
  编写一个售票系统，三个窗口，每个窗口独立售票，所售票不能有重号。并且优先次序为1号窗口卖1-5号，2号窗口卖6-10号，3号窗口卖11-15号。

3.实验要求
  请完成下列代码：
   class MyThreadR implements Runnable{

 

     // 你的代码（注意，上面的代码属于MyThreadR类，下面的代码属于Main类）
     
       th1.start();
       th1.sleep(3000);
       th2.start();
       th2.sleep(3000);
       th3.start();
     }
  }

Output Description

Win1 sales 1 ticket
Win1 sales 2 ticket
Win1 sales 3 ticket
Win1 sales 4 ticket
Win1 sales 5 ticket
Win2 sales 6 ticket
Win2 sales 7 ticket
Win2 sales 8 ticket
Win2 sales 9 ticket
Win2 sales 10 ticket
Win3 sales 11 ticket
Win3 sales 12 ticket
Win3 sales 13 ticket
Win3 sales 14 ticket
Win3 sales 15 ticket

 

ac代码：

 static int num = 0;
    int ticketnum = 15;
    public void run(){
        for (int i = 0; i < 5; i++) {
            num++;
            if( num<=ticketnum ) {
                System.out.println(Thread.currentThread().getName() + " sales " + num + " ticket");
            }
        }
    }
}
class Main{
    public static void main (String[] args)throws InterruptedException {
        MyThreadR th = new MyThreadR();
        Thread th1 = new Thread(th,"Win1");
        Thread th2 = new Thread(th,"Win2");
        Thread th3 = new Thread(th,"Win3");
