Write a class in Java called WordLists 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 word lists (the arrays of strings) to text files.
