Answer 1

Hey There!!


Here is a program which will work for any number of digits:

import java.util.Scanner;
public class DigitCount
{
    public static void main(String[] args)
    {
        Scanner sc = new Scanner(System.in);
       
        System.out.print("Enter a number: ");
        int n = sc.nextInt();
       
        int d=0;
       
        while(n!=0)
        {
            n = n/10;
            d++;
        }
       
        System.out.println("Number of digits is: "+d);
    }
}
