# Java Program To Sum The Digits In An Integer

The program below is the answer to Liang's Introduction to Java Programming (9th Edition) Chapter 2 Exercise 2.6.

Question: Write a program that reads an integer between 0 and  1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14. Hint: Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 / 10 = 93.
