Sample Output:

alist of books needed for courses as well as a list of related tradebooks of interest to the major l. Design an abstract class Book to model a book at a university book store. Each book contains a title, author, ISBN number, and wholesale price. A default constructor is needed for an empty book. A parameterized constructor is passed arguments. Accessors and mutators for all data members are needed Abstract method retailPrice returns the retail price 2. Design a class Textbook derived from Book. A textbook adds a data member for course associated with the textbook (ex. Cos225). The retailPrice method returns retail price uses a 10% markup percent (ex. a book with a wholesale price of $100 would have a retail price of $110) A default constructor is needed for an empty textbook. A parameterized constructor is passed all arguments. Accessor and mutator methods are needed for the new data member. 2. Design a class Tradebook derived from Book. A tradebook adds a data member for the major associated with the tradebook (ex. cos). The retailPrice method returns a retail price that uses a 15% markup percent (ex. a book with a wholesale price of $100 would have a retail price of$115) A default constructor is needed for an empty tradebook. A parameterized constructor is passed all arguments. Accessor and mutator methods are needed for the new data member. 3. Design a BooklistGenerator class. This class will use an ArrayList object of Book references to manage books. Data file books.txt contains a list of books where the first line indicates the type of book (Textbook or Tradebook). The last line of a data set lists either the course or the major. Code should work for any valid input file with unknown number of lines. You may assume all data is valid. books txt Notepad File Edit Format View Help Textbook Introduction to Programming with C++ Y. Daniel Liang 0136097200 109.99 COS 221.
