could someone please explain what is going on here:

int sum = 0;
int k = 7146;
do {
sum = sum + k % 10;
k = k / 10;
} while (k > 0);
System.out.println (sum);

finding the sum of the digits of k.
7+1+4+6 = 18

cheers

You can add some println function to print the result out when the loop run everytime. And also you can add the counter to know more clearly, the 1 time is.....the 2 time is ......etc

 
int sum = 0; 
int k = 7146;
do 
{
  sum = sum + k % 10;
  System.out.println (sum);
  k = k / 10;
  System.out.println (k);
} while (k > 0);
System.out.println (sum);
