CatalogDriver Class

Most of the CatalogDriver class is provided to you. To complete its definition, you will need to do the following:

• Create an ArrayList of CatalogItems. The type parameter for the catalog items will be a CD.
• If you haven't declared and initialized an ArrayList before, this is how an ArrayList of Strings would look:
  List<String> stringList = new ArrayList<String>();
Note that the ArrayList object is being referred by a List object.

• Note that creating an array list of Books is syntactically legal just as creating an array list of catalog items each of which is of type a Book. Although you won't get a compiler error, both however are not the same and you should keep a note of this in order to avoid bugs.


• Similarly, create another ArrayList of CatalogItems, where each catalog item is of type Book

The code after the above declarations in the Driver class sorts the ArrayList by calling the private method sort(). If you have a look at the sort() method, it calls the compareTo() method you wrote for each of the catalog items.
