(Sum the digits in an integer) Write a method that computes the sum of the digits in an integer. Use the following method header public static int sumDigits (1ong n) 0.2 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 then displays the sum of all its diaito
