String manipulation help please

Question

I need to write a Java program that will find the sum of the digits in a 7-digit integer. The input has to be taken by JOptionPane in 1 single integer variable.
e.g if the input value was 4209632, my output should look like:
Value = 4209632
and the sum of each digits in 1 variable.
Sum of digits = 26
Please help. I need to use modulus function to do this but i dont know how to get all digits individually out of the single variable and add them together.

Oh, i didn't notice that you want to use the modulus function...it's not necessary, but if you have to use it for some reason, than use the Integer class to help.
Use the static methord parseInt(String s) of the Integer class to get an int value of a string. parseInt return an int with the integer value of the string s.
Here is the syntax:
int intValue = Integer.parseInt(numericString);
