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);

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
 
Then YOU must do the pig's work! Read this tiny ad. READ IT!
