Small Java Fix?

Hi, I have finished the code for an assignment but I cannot seem to get the program to run. The code may not be right, but the assignment is quite easy, and having my code basically means you can just fix the small mistakes (or change everything if my code is bad). I will attach my my code and here is the assignment: Scrabble Help: The [login to view URL] file attached here 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 array of words of length n. startsWith(int n, char firstLetter): returns an array of words of length n beginning with the letter firstLetter containsLetter(int n, char included): returns an array of words of length n containing the letter included but not beginning with it. vowelHeavy(int n, int m): returns an array of words of length n containing at least m vowels. multiLetter(int m, char included): returns an array of words with at least m occurrences of the letter included. Write a test class for your WordLists class that tries these methods out and writes the wordlists (the arrays of strings) to text files.
