Java Program to break Integer into Digits

In this tutorial, we will write a java program to break an input integer number into digits. For example if the input number is 912 then the program should display digits 2, 1, 9 along with their position in the output.

Java Example to break integer into digits

Here we are using Scanner class to get the input from user. In the first while loop we are counting the digits in the input number and then in the second while loop we are extracting the digits from the input number using modulus operator.

package com.beginnersbook;
import java.util.Scanner;
public class JavaExample 
{
    public static void main(String args[])
    {
        int num, temp, digit, count = 0;
        
        //getting the number from user
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter any number:");
        num = scanner.nextInt();
        scanner.close();
        
        //making a copy of the input number
        temp = num;
        
        //counting digits in the input number
        while(num > 0)
        {
            num = num / 10;
            count++;
        }
        while(temp > 0)
        {
            digit = temp % 10;
            System.out.println("Digit at place "+count+" is: "+digit);
            temp = temp / 10;
            count--;
        }
    }
}

Output:
