3. Implementation of WRITE FILE code, that executes whenever user requests to ADD a Book.
4. Implementation of a SORT Method in the Library Class, that sorts the Book List alphabetically by title.
5. Implementation of a REMOVE Method in the Library Class that removes a Book from the file.
6. It needs to read ALL the books from the file, loop through the ArrayList to find the textbook to be removed. Remove the textbook and WRITE the ArrayList of books back to File.
7. Create a Fiction and Nonfiction class that inherits Book. Look for the “Super
