Im not quite under standing the following Code, I have the enum file and understand that part, but I am struggling with taking in the object, then searching the arrayList for that object, and then how would I add the new object to the array.

addBook(Book book)

If the Reader already has a copy of book addBook returns a Code.BOOK_ALREADY_CHECKED_OUT_ERROR;

Otherwise add the book to the List of books in the reader object and return a Code.SUCCESS;
