Consider the following class hierarchy: class Animal { ... } class Mammal extends Animal { ... } class Cat extends Mammal { ... } Write a generic method printArray that takes an array of any type and prints each element of the array. If the element is an instance of Animal or its subclass, the method should call the toString method of the object to print its details. Otherwise, the method should simply print the element. Your method should have the following signature: public static void printArray(T[] array)
