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();
}
}
