# Finding Number of Digits in a Number

The following Java program finds the number of digits in a number. This program converts the number to a string and then prints its length,

public class DigitsInNumber { public static void main(String[] args ) { int number = 94487; String s = String.valueOf(number); System.out.println(number + " has "+ s.length()+" digits"); } }

The following is an alternate Java implementation which finds number of digits in a number without converting it into a string. This program divides the number by 10 until the number becomes 0. The number of iterations is equal to the number of digits.

public class DigitsInNumber { public static void main(String[] args ) { int original_number = 1119; int n = original_number; int digits = 0; while(n > 0 ) { digits ++; n = n / 10; } System.out.println(original_number + " has "+ digits+" digits"); } }
