import java.util.*;
public class Time extends Thread{
public void run(){
int h,m,s;
while(true)
{
h = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);
m = Calendar.getInstance().get(Calendar.MINUTE);
s = Calendar.getInstance().get(Calendar.SECOND);
System.out.print("当前系统时间为："+"h:"+"m:"+"s");
try{ Thread.sleep(100); }catch(Exception e){}
}
}
public static void main(String args[]){
Thread th = new Thread();
th.start();
}
}
是哪个地方不对啊？谢谢！
