The purpose of this assignment is to develop your ability to code GENERIC classes and methods and to understand how the ArrayList data structure dynamically adjusts its capacity to store objects. We will do this by taking a do-it- yourself (DIY) approach by building our own ArrayList-Like data structure called "ArrayBox". This assignment has its own set of slides that we discussed in class. Those slides are available in Moodle under "Slides" and are entitled simply "arraybox.pdf". Refer to that presentation for details of what needs to be replicated. In general, you must: Create a generic class called ArrayBox that uses a STATIC array of SIZE 2 elements only. Also have the class contain an index variable that refers to the index of the next available spot in your array that can contain an object. Your ArrayBox declaration needs to look similar to this: public class ArrayBox
private E[)elements = (ED) (new Object[2]); private int end_idx = 0; within this class implement the following public methods declared EXACTLY AS: public int size) public boolean add Ee) public Eget(int index) public E set(int index, E element) public E remove(int index) You may add additional private methods as you wish to modularize the code better but the above methods must be in your class. in addition you must create code that will resize the static array as needed as described in class. Namely, if a call to the add() method realizes the static array is FULL then your code must recreate a new array doubled in size before completing the add() request. Again refer to the slides "arraybox.pdf". Create a Driver class called ArrayBoxDriver (this will contain your main method). Have this class create an instance of ArrayBox of data type and call a mainMenu() method: public class ArrayBoxDriver { private ArrayBox box = new ArrayBox(); public static void main(String[] args) mainMenu(); then have this class produce a "menu" that looks similar to this: =[==[==[= (================================)=)= )= =[==[==[=[ Welcome to ArrayBox =)==]=>] = ) EEEEEEEEEEEEEEEEEEEE =====] =]==] ==) = Choose... 1. Add an element(String) to our box. 2. Remove an element(String) from our box. Choose... 1. Add an element(String) to our box. 2. Remove an element(String) from our box. 3. Replace(set) an element(String) from our box. 4. List the contents of the box. 5. Exit program Now complete the program by coding the menu options 1-5 above. In order to help you understand exactly what your program should do (inputs and outputs), I have included a runtime version of this assignment.
