Java Program To Break Integer into Digits

In this Java Program, we break Integers into Digits

Here we use Scanner class to get input from the user. First While loop is use to count the digits in the input number and second while loop is use to extract the digits from the input number using modulus operator.

Step 1 : Import Scanner Class

Step 2 : Create a Class IntegerToDigit

Step 3 : Create main method

Step 4 : Initialize num, temp, digit and count and store 0 in count

Step 5 : Ask the user to enter any number

Step 6 : Store the user entered number into num variable

Step 7 : Close the Scanner class to avoid memory leaks

Step 8 : Create a copy of input number

Step 9 : Store the num into temp

Step 10 : Count the digits into the input number

Step 11 : Apply While loop where num is greater than zero

Step 12 : Divide num by 10 and store the result into num variable

Step 13 : Increment count by one.

Step 14 : Apply another while loop where temp is greater than zero and store the result of temp % 0 into digit.

Step 15 : Print the Digit

Step 16 : Divide temp by 10 and store the result into temp variable

Step 17 : Decrement count by one.

Program :

import java.util.Scanner;

public class IntegerToDigit {

    public static void main(String[]args)

    {

        int num, temp, digit, count = 0;

        //getting the number from user

        Scanner sc = new Scanner(System.in);

        System.out.print("Enter any number:");

        num = sc.nextInt();

        sc.close();

        //creating a copy of the input number

        temp = num;

        //counting digits int 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 :

Enter any number:7891

Digit at place 4 is:1

Digit at place 3 is:9

Digit at place 2 is:8

Digit at place 1 is:7
