# sum of digits java

﻿6.2) (Sum  the digits in an integer ) Write a method  that computes the sum  of the digits in aninteger . Use the following method  header:
public static int  sumDigits(long n)
For example, sumDigits(234) returns 9 (2 + 3 + 4). (Hint: Use the % opera- tor to extract digits, and the / operator  to remove the extracted digit. For instance, to extract 4 from 234, use 234 % 10 (= 4). To remove 4 from 234, use 234 / 10 (= 23). Use a loop to repeatedly extract and remove the digit until  all the digits are extracted. Write a test program  that prompts the user to enter an integer  and displays the sum  of all its digits.
