1. Add a new method to BagInterface labbeld, toArrayList() that should return all objects contained in the bag as an arrayList.

2. In class ResizableArrayBag implement method toArrayList

3. Create a new class Book that has the following properties/data and behaviors/methods

Properties:

author, title, numberOfPages

Methods:

- default constructor: sets all data members to their default values

- constructor with 3 parameters, that initializes the data members accordingly.

- Getter methods for all 3 data members

- toString: returns a string containing all data members each prefixed with a description of the data member.

4. Create a new class BookStore to test all methods of Book, and some of the BagInterface and ResizableArrayBag, more specifically from BagInterface methods add, remove, toArray & toArrayList and from ResizableArrayBag, all prior methods in addition to the default constructor.

a. Test1, tests the Book methods

i. methodA(), Create a book using default constructor then print object using toString. [check printed results correct or not]

ii. methodB(), Create book using constructor with 3 parameters, then print object to screen using toString method. [check printed results correct or not]

iii. methodC(), Create book using constructor with 3 parameters, then print object to screen using the getter methods. [check printed results correct or not]

b. Test2, test Book, BagInterface and ResizableArrayBag methods .

i. methodD(), Create a bag then add several books in it, then print all objects of the bag by looping and calling remove() in BagInterface [check printed results correct or not]

ii. methodE(),Create a bag then add several books in it, then print all objects of the bag by calling toArray() method and printing the contents of the returned array. [check printed results correct or not]

iii. methodF(),Create a bag then add several books in it, then print all objects of bag by calling toArrayList() method and printing the contents of the returned arrayList. [check printed results correct or not]

5. Upload your homework to moodle as a zip file containing the source code files for BagInterface, ResizableArrayBag , Book and BookStore.
