sum of output

Question

Hey
How can we sum numbers in the output of code below.
Thanks

import java.util.Scanner;

public class IDCode{
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.println("Enter ID Code:");

int x = input.nextInt();
String s = Integer.toString(x);
System.out.println(s.length()==10?true:false);

int b = 0; int c = 10; int sum = 0;

for(int i = 0; i < s.length();i++){
b = Integer.parseInt(""+s.charAt(i))*c;
System.out.println(b);
--c;
}

}
}

Answer 1

sum += b;
At the end of the loop.
