package byetickets;

    private int tickets=1;//票数

@Override

public void run()   {

         while(true){

        synchronized (this) {

break;

}

System.out.println(Thread.currentThread().getName()   + "出售了第" + tickets + "张票!");

1.2售票点的模拟

package byetickets;

public class Test01   {

   public static void main(String[]   args) {

  MyThread my=new MyThread();

  Thread t1=new Thread(my,"售票点1");

  Thread t2=new Thread(my,"售票点2");

  Thread t3=new Thread(my,"售票点3");

  Thread t4=new Thread(my,"售票点4");

  t1.start();

  t2.start();

  t3.start();

  t4.start();

   }

}
