- Scrabble Help: 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…Question 40 An application can indicate a specific way to order the elements of a SortedABList list by passing a(n) Comparator object to a constructor of the list class.

- You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…What is the difference between ArrayLists and arrays?34Given that values is of type LLNode<Integer> and references a linked list (non-empty) of Integer objects, what does the following code do if invoked as mystery(values)? void mystery(LLNode<Integer> list){if (list != null){System.out.println(list.getInfo());mystery(list.getLink());}}Group of answer choicesprints the list from start to end.prints the first element on the list.prints the last element on the list.prints the list in reverse order.None of these is correct.

Your function should be able to reverse a list of values of any type. You must use at least one array to solve the problem. Hints: Try breaking down the…
