In this homework problem we’ll begin completing an implementation of SimpleList that uses a linked list of Item objects internally. We’ve provided some starter code in a class called SimpleLinkedList. However, the get and set methods rely on a helper function called getItem to work properly, which is not properly implemented yet. You should create a class called YourSimpleLinkedList that inherits from SimpleLinkedList and provide a correct implementation of getItem. getItem should return a reference to the Item at that position in the list, or null if no such item exists. You may want to look at the implementation of size in SimpleLinkedList for a reminder of how to walk a linked list using a for loop. You will also need to provide a constructor for YourSimpleLinkedList that takes an array of Object references and simply passes them to a call to super to properly initialize SimpleLinkedList. A portion of the implementation of SimpleLinkedList follows:
