Question

Sum of Odd and Even Digits

Problem Statement :

Write a java program to calculate the sum of odd and even digits in a number. The input consists of a single integer 'n' which corresponds to the given number.The output must display the sum of odd numbers and even numbers.

Problem Constraints:

The datatype of integer must be long.

The file name must be Main.java

Sample Input and Output :

Enter the number

3924209420352

The sum of the odd digits are 29

The sum of the even digits are 16

 

Answer 1

The solution reads the user input from the standard input as a string. Then iterates through each character, converts them to integers and add it to the right sum depending on if digit is even or odd.

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

System.out.println("Enter the number");

Scanner scanner = new Scanner(System.in);

String input = scanner.nextLine();

scanner.close();

int oddSum = 0;

int evenSum = 0;

for (int i = 0; i < input.length(); i++) {

int digit = input.charAt(i) - '0';

if (digit % 2 == 0) {

evenSum += digit;

} else {

oddSum += digit;

}

}

System.out.printf("The sum of the odd digits are %d\n", oddSum);

System.out.printf("The sum of the even digits are %d", evenSum);

}

}
