Write a method public static doubled get Array Stats double

Write a method public static doubled [] get Array Stats (double[] a) that finds the minimum, average, and maximum elements in the array a. Your method should return an array containing a\'s minimum element in index 0, a\'s average value in index 1, and a\'s maximum element in index 2.
