WRITE THE PSEUDOCODE TO SOLVE THE FOLLOWING PROBLEM

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 $2+3+4=9$
