Lesson 34 Activity 2

/*
 * Lesson 34 Coding Activity 2
 *
 * For the Lesson 34 activities, you will be asked to write one or more methods.
 * Use the template to write a main method that tests each of your methods,
 * then paste everything into the code runner box. Your submission should
 * begin with the first import statement and end with the final }.
 *
 * Write a method that takes an array of ints as a parameter
 * and returns the average value of the array as a double.
 *
 *     public static double average(int [] a)
 *
 * For example, average(a) would return 2.0
 * if a = {1, 2, 3} or 1.0 if a = {1, 1, 1}.
