如何使用線程完成售票系統

如何使用多線程處理賣火車票

public class Windows  implements Runnable{
	 int ticket=100;
	Object obj=new Object();
	public void run() {
		while(true) {
			synchronized (obj) {
				try {
					Thread.sleep(2000);
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				if(ticket>0) {
					System.out.println(Thread.currentThread().getName()+"售票，票号為"+ticket--+"---------還剩"+ticket+"張票");
				}else {
					break;
				}
			}
		}
	}

}

ublic static void main(String[] args) {
	//
	Runnable runnable=new Windows();
	Thread t1=new Thread(runnable);
	Thread t2=new Thread(runnable);
	Thread t3=new Thread(runnable);
	t1.setName("視窗1");
	t2.setName("視窗2");
	t3.setName("視窗3");
	t1.start();
	t2.start();
	t3.start();
	}
}
