- What is an annotation? How are annotations useful in writing our ArrayList<E> class?Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat BirdWrite the following method that returns an ArrayList from a set:public static <E> ArrayList<E> setToList(Set<E> s)

- What is the ArrayList list's starting size?public static ArrayList findExactString(String s, ArrayList myArray) { return null; } // Use the above method, findExactString, as a helper method to implement addWithoutDuplication method. The addWithoutDuplication method has the following properties: 1- It takes two arguments, a string s and an ArrayList myArray of type string. 2- It returns an integer which represents the number of occurrences of the string s in myArray while attempting to add it. 3- If myArray is null, it returns -1 4- If adds the string s to the end of the ArrayList myArray if the string s is not already there. public static int addwithout Duplication(String s, ArrayList myArray) { return -1;8. To create a list to store integers, use a. ArrayList list = new ArrayList() ; w w b. ArrayList list = new ArrayList(); www c. ArrayList list = new ArrayList(); d. ArrayList list = new ArrayList(); w w
