Write, Compile and Execute a Java 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). (Hint: Use the % operator 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 àre extracted. Write a test program that prompts the user to enter an integer and displays the sum of all its digits.
