class Ticket extends Thread{
private int tick = 100;
public void run(){
while(true){
if(tick>0){
System.out.println(Thread.currentThread().getName()+" ....sale :"+tick);
}
}
}
}
class TicketDemo {
public static void main(String[] args) {
// TODO 自动生成的方法存根
Ticket t1 = new Ticket();
Ticket t2 = new Ticket();
t1.start();
t2.start();
}
}
在第一行class Ticket extends Thread中Ticket下划线，报错，请问哪里出错了？
