We are going to create a library application. You can borrow books and/or DVDs from the library. The objects that you want to borrow all have a barcode (a series of numbers, id in your csv files) and a title. Furthermore, books have an ISBN number (text) and an author. DVDs, besides barcode and title, also have a rating and a year of release.
The library contains a list of books and a list of DVDs, where each item to be loaned (i.e. book or DVD) knows whether it has been loaned out (or not). The lists of both books and DVD’s must be read from the supplied files “books.csv” and “dvds.csv” respectively (see Files).
At the start of the application, all objects are automatically loaded from the csv files. After that, the librarian (the user) has the possibility to:
In the output below, we visualised lent objects with an *.
Of course, your program should ensure that when lending out or taking back books, only a list of the relevant books is shown. Also, throw proper exceptions if something illegal is attempted.
Hint: Remember the
OptionSelectorexercise from ealier? Try to understand why such a class would make your life easier (and use it in your solution!).
Below we have given you a possible output for your application. Obviously your layout may differ a little as long as the functionality remains the same.
Read 6 books and 6 dvds!
