创建多线程的第二种方式

使用Runnable接口，三个共用一个对象

package deep;

class Window1 implements Runnable {
    private int ticket = 100;

    public void run() {
        while (true) {
            if (ticket > 0) {
                System.out.println(Thread.currentThread().getName() + ":卖票：票号为:" + ticket);
                ticket--;
            } else {
                break;
            }
        }
    }
}

public class WindowTest1 {
    public static void main(String[] args) {
        Window1 w = new Window1();

        Thread t1 = new Thread(w);
        Thread t2 = new Thread(w);
        Thread t3 = new Thread(w);

        t1.setName("窗口一");
        t1.setName("窗口二");
        t1.setName("窗口三");

        t1.start();
        t2.start();
        t3.start();
    }
}
