                        /细说多线程之Thread VS Runnable

请问继承方法实现线程，实例化的时候只new一个线程而不是三个，难道不也是只卖五张票？

public class Ticket extends Thread {
    private int tic = 5;

    @Override
    public void run() {
        while (tic > 0) {
            --tic;
            System.out.println(Thread.currentThread().getName() + "剩下" + tic + "张票");
        }
    }

    public static void main(String[] args) {
        Ticket ticket = new Ticket();
        Thread thread1 = new Thread(ticket, "线程1");
        Thread thread2 = new Thread(ticket, "线程2");
        Thread thread3 = new Thread(ticket, "线程3");
        thread1.start();
        thread2.start();
        thread3.start();
    }
}
