import java.util.Scanner; public class DigitAdditionCalc { public static void main(String args[]) { int number, remdr=0, total=0, tempNum; Scanner scan = new Scanner(System.in); System.out.print("Enter a Number : "); number = scan.nextInt(); tempNum = number; while(number>0) { remdr = number%10; total = total+remdr; number = number/10; } System.out.print("Sum of digits of number " +tempNum+ " is " +total); } } |
Output:
Enter a Number : 5385
Sum of digits of number 5385 is 21
Sum of digits of number 5385 is 21
That’s all about Java program to add digits of number.
