import java.util.*;

public class Main

{

 public static void main(String[] args) {

    Scanner sc=new Scanner(System.in);

    System.out.print("enter the number=");

    int num=sc.nextInt();

    digit obj=new digit();

    obj.number(num);

 }

}

class digit{

    int rm,cn=0;

    void number(int n){

     while(n>0){

         rm=n%10;

         cn+=1;

         n/=10;

     }

     System.out.println("digits in number="+cn);

     System.out.print("the square of no. of digits in number="+(cn*cn));

    }

}

■》output->

enter the number=56704

digits in number=5

the square of no. of digits in number=25
