### Java Program to Count Number of Digits in an Integer - The Coding Shala

Home >> Java Programs >> Count Number of Digits in an Integer In this post, we will learn how to count the number of digits in an integer using a Java program. Java Program to Count Number of Digits in an Integer You have given an integer, return the number of digits in that using Java program. The given number is above 0. Example 1: Input: 34 Output: 2 Example 2: Input: 01 Output: 1 Approach When we divide a number by 10, we get one digit or we remove one digit from a given number so here we will be using a loop and divide the given number by 10 until it becomes 0. Example: The number is 23, so after first iteration number = 23/10 = 2, and count = 1 second iteration => number = 2/10 = 0, count = 2. Java Program: import java.util.Scanner ; /** * https://www.thecodingshala.com/ */ public class Main { public static void printDigits ( int num ) { System . out . print ( "Number of Digits in " + num + " are: &q
