1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

import java.io.*; class sumofdigit{  public static void main(String [] args) {     try{     BufferedReader din=new BufferedReader (new InputStreamReader(System.in));         int n,r,s;    System.out.println("Please enter the number to find the sum of a digit: ");         n=Integer.parseInt(din.readLine());    r=0;    s=0;         while(n>0){     r=n%10;     s=s+r;     n=n/10;    }         System.out.println("The sum of the digit is : " +s);   } catch(IOException e) {    System.out.println("Wrong Input");         }   } }

Output of sumofdigit Program:
Please enter the number to find the sum of a digit: 12345

The sum of the digit is : 15
