Your code runs and the tests provided appear to work, so technically this submission is functional. You also created a class with five fields, included constructor validation, and added custom methods.

However, there are several assignment requirement issues:
• Your class was created inside object.example.derwinbell. The assignment specifically said not to modify the object.example package and to create your work inside your own package.
• The assignment requires getters and setters for all fields, but this class only has getters.
• Your tests do not fully cover all required behaviors. For example, returnBook() is not tested.
• The assignment also asked for tests covering all getters/setters and for the AAA pattern to be visible in every test.

Please make sure future submissions follow the package directions exactly and fully match all listed lab requirements.
