Question: This is java problem. I have writen the codes i am not sure what i do wrong, please fix it or add to make it

This is java problem. I have writen the codes i am not sure what i do wrong, please fix it or add to make it works. I am not sure what did i do wrong and why it wont compile this is the direction:

-The Book class models information common to all books.

-The LibraryBook class is a Book, but library books also have a call number, and the call number allows books to be ordered on the shelves. (The ordering is given by a compareTo specified in the Comparable interface. In addition, because many library books can circulate (be checked out and returned), each library book has a circulation status (e.g., on shelf, checked out, permanently in reference collection).

-A ReferenceBook is a type of Library Book that is housed in a specified collection (e.g., a reference area in Tioga, or in the Snoqulamie Building), and reference books do not circulate.

-A CirculatingBook is a type of Library Book located on the shelves until it is checked out, and the book is placed back on the shelves when it is returned.
