这个哪里有问题呀

public java.util.*;
public class liu{
    public static void main(String[] args){
        Scanner in=new Scanner(System.in);
        System.out.println("请输入你的名次");
        int mingci=in.nextInt();
        switch(mingci){
            case 1:
            System.out.println("盟主");
            break;
            case 2:
            System.out.println("掌门");   
            break;
            case 3:
            System.out.println("逐出师门");
            break;
            default:
            Syetem.out.println("滚蛋");
        }
    }
   
}
