Exercise : percentEven

Write a method named percentEven that accepts an array of integers as a parameter and returns the percentage of even numbers in the array as a real number. For example, if a variable named nums refers to an array of the elements {6, 2, 9, 11, 3}, then the call of percentEven(nums) should return 40.0. If the array contains no even elements or no elements at all, return 0.0.
