java_简单的售票系统

通过对多线程的学习，模拟了一个简单的售票系统

class Ticket implements Runnable

{

 private int tick=TicketSealCenter.num;

 Object obj = new Object();

 public void run()

 {

  while(true)

  {

   synchronized(obj)

   {

    if(tick>0)

    {

     String name = Thread.currentThread().getName();

     int windows = Integer.parseInt(name.substring(7, name.length()));

     try{Thread.sleep(100);}catch(Exception e){}

     System.out.println("第"+(windows+1)+"窗口卖出了第"+tick--+"张票");

    }

   }

   

  }

 }

}

//售票窗口通过for循环控制窗口数量

class SealWindow

{

 public static void addWindow()

 {

  Ticket t = new Ticket();

  for(int x=1;x<=4;x++)

  {

   Thread t1 = new Thread(t);

   t1.start();

  }

 }

}

//售票中心控制票数

class TicketSealCenter

{

 public static int num=100;

}

public class ThreadDemo2

{

 public static void main(String[] args)

 {

  SealWindow.addWindow();

 }

}
