Write a Java program in which a recursive method with the following signature public static int Sum2 (int n) that computes the sum of the squares of the digits in a positive integer n is defined. Your program will ask the user to input a positive integer, invoke the method, and display the sum of the squares of the digits in the input positive integer. For example, if the input is 2011, then your program should display 6 (i.e., 2*2 +0 0+1*1 + 1*1).
