LinkedListBox

Specifically, implement your generic classes as:

public class LinkedListNode { public E element; public LinkedListNode next; } public class LinkedListBox { public LinkedListNode head; public LinkedListNode tail; public int count = 0; }

Within the LinkedListBox class, implement the following methods:

public boolean add(E e). Returns true after adding an element to the end of the list.

public E get(int idx). Returns element at index position idx.

public E set(int idx, E e). Changes the element at position idx to e. Returns old element.

public E remove(int idx). Removes element at position idx from the list and returns it.

public int size(). Self-explanatory

public boolean isEmpty(). Self-explanatory

public Integer find(E e). Search for element e in the linked list and return its index position or return null if not found.

public E removeFirst(). Remove and return the element at the head of the list.

public E removeLast(). Remove and return the element at the tail of the list.

public void addFirst(E e). Add an element to the front of the list.

public void insert(int idx, E e). Insert an element right after the index idx position.

Create a driver class called LinkedListBoxDriver. Provide the user a menu: 1. Add an element(String) to our box. 2. Remove an element(String) from our box. 3. Replace(set) an element(String) from our box. 4. Insert an element(String) after index. 5. List the contents of the box. 6. Exit program
