线程同步的一个问题，求高手指导

Question

public class TestTicket{
public static void main(String[] args){
SellTickets st = new SellTickets();
Thread t1 = new Thread(st,"窗口1--");
Thread t2 = new Thread(st,"窗口2--");
Thread t3 = new Thread(st,"窗口3--");
t1.start();
t2.start();
t3.start();

}

}

class SellTickets implements Runnable{
private int ticket=10;
private synchronized void SellTickets(){

        try{
            Thread.sleep(1000);
          System.out.println(Thread.currentThread().getName() +
           "第 " + ticket + "张票已经售出。" ); 
           ticket--;
           this.wait();
           this.notify();
        }
        catch(Exception e){
    e.printStackTrace();
        }

}
public synchronized void run(){
      while(ticket>0){
         SellTickets();
    } 
        System.out.println(Thread.currentThread().getName() + "票已经售完，正在补票中，请等待。。。");

}
}

输出结果
