Two more.. Java classes needed

i have done lot of classes but I still need two classes for my project. These classes are described below. ---Design and implement appropriate methods for a LoanableManual and write a simple application to test your LoanableManual class. Your amended application should provide additional features which enable a user to: • display all manuals on loan • display all manuals not on loan • borrow a manual • return a manual. -The application should obviously not malfunction if the user should enter incorrect data or perform inappropriate actions such as borrowing a car that is already on loan. Illustrate the use of Exceptions by incorporating rigorous error checking in your application.
