The user will be prompted for the String to be stored in the ArrayList and then hit enter. The user will be able to continue to add items to the ArrayList until they just hit enter without typing anything. Once the user does this (hits enter without typing anything), the program will display all of the elements of the ArrayList, both the index and String values, in a table. It will do this via a single loop making use of an iterator method. 2.
