多執行緒-實現Runnable介面的方式賣電影票案例

package cn.itcast_07;

public class SellTicket implements Runnable {
	// 定義100張票
	private int tickets = 100;

	@Override
	public void run() {
		while (true) {
			if (tickets > 0) {
				System.out.println(Thread.currentThread().getName() + "正在出售第" + (tickets--) + "張票");
			}
		}
	}
}

		// 建立三個執行緒物件
