(Revising Listing 21.1) Revise the GenericStack class in Listing 21.1 to imple- ment it using an array rather than an ArrayList. You should check the array size before adding a new element to the stack. If the array is full, create a new array that doubles the current array size and copy the elements from the current array to the new array. Problem 21.3 asks you to write a generic method that removes duplicate items from an ArrayList. Write your method in a new class called Utilities. Please include a main method for this class that tests your method. Think carefully about the way you test your program. Developing a good test plan is as important as developing the code itself. Obviously, you should show that your generic method works for different types of objects, i.e. ArrayLists or arrays of Integer, Strings, FacebookUsers, etc. You should also test any unusual cases you can think of: what if the ArrayList or array is empty? what if it contains only one item? what if your removeDuplicates method is passed an ArrayList in which every item is identical? etc.
