Description
Improving on the Word Game
Add the following improvements to the word game. (1) The first letter of the subject letters (the first line
of the input file) must be contained in all the correct guessed words. (2) If a guessed word contains ALL
of the subject letters, that is worth 3 points. (3) Display the correctly guessed words in alphabetical
order.
Lists of Words
Create a class called WordNode which has fields for the data (a Word) and next (WordNode) instance
variables. Include a one-argument constructor which takes a Word as a parameter. (For hints, see the
PowerPoint on “Static vs. Dynamic Structures”.)
public WordNode (Word w) { . . }
The instance variables should have protected access.
Create an abstract linked list class called WordList. This should be a linked list with head node as
described in lecture. Modify it so that the data type in the nodes is Word. The no-argument constructor
should create an empty list with first and last pointing to an empty head node, and length equal to zero.
Include an append method in this class.
Create two more linked list classes that extend the abstract class WordList: One called
UnsortedWordList and one called SortedWordList, each with appropriate no-argument constructors.
Each of these classes should have a method called add(Word) that will add a new node to the list. In
the case of the UnsortedWordList it will add it to the end of the list by calling the append method in the
super class. In the case of the SortedWordList it will insert the node in the proper position to keep the
list sorted.
Instantiate two linked lists, one sorted and one unsorted. Add the solutions from the input file to the
unsorted linked list. This list will be searched to see if a guessed word matches. As words are correctly
guessed, add them to the sorted list and display the contents of that list in the TextArea for the guessed
words. Check the method setText in class TextArea to update the contents of the TextArea.
Submit a jar file.
Rather than upload all the files for this project separately, we will use Java’s facility to create the
equivalent of a zip file that is known as a Java ARchive file, or “jar” file.
Instructions on how to create a jar file using Eclipse are on Blackboard. Be sure to include source files
(.java files), not class files in your jar. Create a jar file called Project2.jar and submit that.
