Scanner sc=new Scanner(System.in);
System.out.println("请输入一个10位以内的数字");
long num=sc.nextInt();
int count=0;

while (num>0){
    count++;
    num=num/10;
}
System.out.println(count+"位数");

public class HelloWorld{
public static void main(String[] args){
int num = 999;
int count = 0;
for(int x=1;x<=num;x*=10){
if(x<=num/10){
continue;
}
for(int i=1;i<=x;i*=10){

count++;

}
}
if(num==0){
count+=1;
}
System.out.println("它是个"+count+"位的数！");

}
}
