Generic Classes
Doubly Linked List
Ordered Doubly Linked List
Iterators
Comparators
Your assignment is to write a generic doubly-linked list class and a generic sorted doubly-linked list class that inherits from your generic doubly-linked class. There is no additional GUI required for this assignment. Your list classes will be tested with Junit tests.
BasicDoubleLinkedList class
This generic doubly-linked list relies on a head (reference to first element of the list) and tail (reference to the last element of the list). Both are set to null when the list is empty. Both point to the same element when there is only one element in the list. A node structure has only three fields: data and the prev and next references. The class must only define the following entities: an inner class Node, an inner class that implements ListIterator (for the iterator method), head and tail references and an integer representing the list size. However only the next(), hasNext(), previous() and hasPrevious() methods of the ListIterator that you are required to implement. The rest of the methods can return can throw the UnsupportedOperationException, such as:
public void remove() throws UnsupportedOperationException{
throw new UnsupportedOperationException();}
All the entities are defined as protected so they can be accessed by the subclass. Follow the Javadoc that is provided.
SortedDoubleLinkedList class
A generic sorted doubly-linked list constructed using a provided Comparator. It extends BasicDoubleLinkedList class. Follow the Javadoc that is provided.
Exception Handling
UnsupportedOperationException – this exception is a Java library exception and will be returned by the addtoFront and addToEnd implementations of the SortedLinkedList class and by the remove method of the iterator.
NoSuchElementException – this exception is a Java library exception and will be returned by the next function within the iterator class when there are no more elements in the linked list.
Deliverables:
Java files – The src folder with your driver (javafx application), data element, data manager and Junit Test (.java) files
Javadoc files – The doc folder with your javadoc for student generated files
