NOTICE THAT YOU ARE ONLY WRITING A CLASS $-$ on exams you may be asked to write a class or a program. Make sure you know the proper format for each.

Write a class with a main method $[$test program$]$ that prompts the user to enter an integer and displays the sum of all the integers in that number. You must write a recursive method that computes the sum of the digits in an integer and use the following method header:

public static int sumDigits$($long $n)$

Example

sumDigits$(234)$ returns $2+3+4=9$
