The file dictionary.txt contains all of the words in the Official Scrabble Player's Dictionary, Second Edition.
Note: this list contains some offensive language.
Write a class, WordLists, in Java that generates useful word lists for scrabble players using this list.

Your class should contain the following methods:

• WordLists(String fileName): a constructor that takes the name of the dictionary file as the only parameter.


• lengthN(int n): returns an ArrayList of all length
  n
  words (Strings) in the dictionary file.


• endsWith(char lastLetter, int n): returns an ArrayList of words of length
  n
  ending with the letter
  lastLetter
  


• containsLetter(char included, int index, int n): returns an ArrayList of words of length
  n
  containing the letter
  included
  at position
  index. So for example the word "cannon" would be on the list returned by containsLetter('o',6,4) because it contains the letter 'o', at index 4, and is length 6.


• multiLetter(int m, char included): returns an ArrayList of words with at least
  m
  occurrences of the letter
  included.

Use the included template for your WordLists.java file. Write your own test class, WordTest.java for your WordLists class that tries these methods out and writes the word lists (the ArrayLists of strings) to
text
files.

What to hand in:

A Template for the WordLists.java file is in the Programming Project 5 workspace on Codio. You must write your own test class called WordTest.java (separate file with main method) that tests each of your methods and writes the results to a text file. In addition to the source files include a text file named readMe.txt with an explanation of how your program works. That is, write in plain English, instructions for using your software, explanations for how and why you chose to design your code the way you did. The readMe.txt file is also an opportunity for you to get partial credit when certain requirements of the assignment are not met.
