Scanner及数字数量判断

import java.util.Scanner;

public class Mj{
public static void main(String[]args){
Scanner input=new Scanner (System.in);
int []shuzu=new int[2];
//int q=1;
int w=0;
int e=0;
//System.out.println("请输入QQ号码");
for(int i=0;i<shuzu.length;i++){
System.out.println("请输入QQ号码");
shuzu[i]=input.nextInt();

}
e=shuzu[1];
for(int q=0;q<1;q--){

// e=e/10;
w++;
e=e/10;
// System.out.println("w为"+w);
// System.out.println("e为"+e);
if(e<1)
break;


}
System.out.println("QQ号码为"+shuzu[0]);
System.out.println("QQ号码为"+w+"位数");
// System.out.println(e);
// System.out.println(w);
}
}
