Sum of All Odd Numbers in Java

 Machine Problem

Write a program that uses a loop to compute the sum of all odd digits of an input.  (For example, if the given number is  6741, the sum would be 7 + 1 = 8.)

    System.out.print("\tGive a Number : ");

    int num = input.nextInt();

    int y = num;

    

    while (num > 0) {

        int digit = num % 10;

        if (digit % 2 != 0) {

     display_result += digit;

   }

        num /= 10;

}

    System.out.println();

    System.out.printf("\tThe Sum of %d odd digits is %d", y, display_result);

    System.out.println("\n");

    System.out.print("\tEnd of Program");

    System.out.println("\n");

    input.close();

}
