（非正式管理系统，任务导向型。）

Introduction
This will be done in the form of a library system that allows users to borrow various items that the library holds. You will be required to create an inheritance structure to contain all the different types of items the library might hold. In this case there are five different types of items Books, Magazines, Blurays, DVDs and MusicCDs.

You are required to create a library class that manages this system allowing an item to added or removed in addition to allowing a person to borrow an item and return it.
This program is supplied with an incomplete testing program, you must complete the test driver to ensure the completeness of your library system.
You are also required to generate the rest of the classes to describe the items held in your library using a suitable inheritance model in your program.

Description of the System
There are a number of different types of items in the library. There are Books, Magazines, MusicCDs and Movies.
Movies in turn can be DVDs or Blurays. You will need to implement these items as an inheritance structure with
appropriate setter and getter methods in addition to appropriate access permissions. As a starting point:

All items contain an id (String), a name (String), loaned (boolean), borrower (Person), and a cost (double).
All Books will have an author (String)
All Magazines will have distributionCity (String) and a
magazineFrequency (Frequency) based on an enumerated
type which has day, week monthly, quarterly and yearly.
All Movies will have an genre (Genre) based on an enumerated type Genre which has scifi, action, drama and romance
All DVDs will have a region (int)
All Blurays will have region (char) All MusicCD’s will have composer (String) and an artist (String)

In addition to the Library class described, there are also a few other classes needed for this assignment:

A Library contains the list of items (ArrayList of Items) currently held by the library
A Person has a name (String) and an address (String). Library items can be borrowed by a person.
A TestDriver (supplied with incomplete tests) that will test your program.
DuplicateItemException (Supplied). This exception object is Thrown when a duplicate item is inserted into the Library.
ItemNotFoundException (Supplied). This exception object Thrown when an item is not found in the list
In summary you should have 12 classes including the TestDriver.

Error Handling
To complete the assignment effectively there are some rules regarding exceptions:

In the event that an input is incorrect an Exception should be thrown. Eg invalid region for a bluray or dvd.
If you try to find an item that doesn’t exist you should throw an ItemNotFoundException
If you try to insert an item that already exists you should get a DuplicateItemException
In the event of any other error situations you should throw an exception.

Testing
You are to write a series of tests to make sure your program is uncrashable. You should do this in a test document (a text document included in your project called test.txt). That document should list each method in library with the tests that you consider need to be performed. You should then code your test conditions in the testDriver class. When you run your program you should have the following form of output.
Testing addItem***
-Test add an item and see if it is in the list-
Expected Found
Got Found
Success
-Test adding a new item then retrieving an item that doesn’t exist-
Expected Not Found
Got Not Found
Success
**
You should have one test for every scenario you can think of. In the first example above you would call the addItem with a parameter of a new item then would try finding the item. If an item is returned print out found and declare the test a success.
I will give you a basic test driver that you can expand for the assignment.

Restrictions
There are a number of rules you must follow when addressing the requirements for this assignment.

You must use inheritance.
You must have all the named classes (Library, Person, TestDriver and the two Exception objects).
Your Library class must have the methods EXACTLY as specified. I‘ll say this one again Your Library class must have the methods EXACTLY as specified.
If you don’t it wont compile when I dump my testing class in the folder and you will fail the assignment.
