OverloadedMethod.java

/*
Date: 21-JAN-2020
Programmer: Dan Hopp
Description: Create two overloaded methods that return the average of data in 
    an array. Use the following headers:
        public static int average(int[] arr)
        public static double average(double[] arr)

    Invoke both, and print out the results.
