Question:
Write a method that computes the sum of the digits in an integer. Use the following method header:
public static int sumDigits(long n)
For example, sumDigits(234) returns 9 (2 + 3 + 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.
