多线程售票(二)

package cn.thr;
//线程实现的方法二：实现runnable接口.多采用此方法来避免单继承的局限性
//线程的例子：总共有10张票，开两个窗口买票。
class TicketDemo2 implements Runnable {
	int ticket = 20;
	@Override
	public void run() {
		while (ticket >= 1) {
			ticket--;
			System.out.println(Thread.currentThread().getName() + "卖出的票，票号为："+ ticket);
		}
	}
}
public class Ticket2 {
	public static void main(String[] args) {
		TicketDemo2 demo = new TicketDemo2();
		Thread thread1 = new Thread(demo);// 窗口1
		Thread thread2 = new Thread(demo);// 窗口2
		thread1.start();
		thread2.start();
	}
