多线程模拟火车售票

class hello {

	public static void main(String[] args) throws IOException {
		Ticket t = new Ticket();
		new Thread(t).start();// 模拟四个售票窗口同时售票
		new Thread(t).start();
		new Thread(t).start();
		new Thread(t).start();
	}
}

class Ticket implements Runnable {
	int ticket = 100, i = 0;

	@Override
	public void run() {
		synchronized (this) {//线程同步  避免多线程发生冲突

			while (true) {
				// TODO Auto-generated method stub
				if (ticket <= 0) {
					break;
				}
				ticket--;
				i++;
				System.out.println(Thread.currentThread().getName() + "正在售卖第" + i + "号票,剩余" + ticket + "张票");
			}
		}
	}

}

运行结果：
