Sum of Odd Digits of a Number in Java Language

Sum of Odd Digits of a Number in Java Language (updated) – Java program to find the sum of digits of the given number. Now in this post, we will develop a program to calculate the sum of odd digits of a number in Java language program.

Example:- Number = 12345
Then the odd digits in a given number are 1, 3, 5 and therefore sum of odd digits = 1 + 3 + 5 = 9

Procedure to calculate the sum of odd digits in a number

Table of Contents

Take a number
Declare a variable oddDigitSum to store the sum value and initialize it with 0.
Find the last digit of the number
Check that the last digit is odd or not
If it is odd then add it to oddDigitSum variable, else go to next step
Remove the last digit of the number
Repeat the 3 to 6 steps until the number becomes 0.

Calculate the sum of odd digits in a number in JAVA

import java.util.Scanner;

public class SumOfOddDigitsProgram {

  public static int findOddDigitSum(int number) {

     // declare variables
     int lastDigit = 0;
     int oddDigitSum = 0;

     // loop to repeat the process
     while(number!=0) {

         // find last digit
         lastDigit = number%10;

         // check last digit odd?
         if(lastDigit % 2 != 0) {
            // add it to sum
            oddDigitSum += lastDigit;
         }

         // remove last digit of number
         number = number / 10;
      }

      // return sum value
      return oddDigitSum;
  }

  public static void main(String[] args) {

      // declare variables
      int number = 0;
      int sumOfOddDigits = 0;

      // create Scanner class object 
      // for reading the values
      Scanner scan =  new Scanner(System.in);

      // read inputs
      System.out.print("Enter an integer number::");
      number = scan.nextInt();

      // find sum of digits of number
      sumOfOddDigits = findOddDigitSum(number);

      // display result
      System.out.println("The sum of odd digits of"+
          +" the number "+number+" = "+ sumOfOddDigits);

      // close Scanner class object
      scan.close();
  }
}

OUTPUT



Enter an integer number:: 12345
The sum of odd digits of the number 12345 = 9
