Using an inheritance hierarchy, design a Java program tomodel items at a library (books, journal articles, videos and CDs.) Have anabstract superclass called Itemand include common information that the library must have for every item (suchas unique identification number, title, and number of copies). No actualobjects of type Itemwill be created ­ each actual item will be an object of a (non­abstract)subclass. Place item­type­specific behavior in subclasses (such as a video'syear of release, a CD's musical genre, or a book's author). More in detail:

1.Implement an abstract superclass called Item and define all commonoperations on this class

(constructors, getters, setters, equals, toString, print, checkIn, checkOut, addItem, etc). Have private datafor: identification number, title, and number of copies.

2.Implement an abstract subclass of Item named WrittenItemand define all common operations on thisclass. Added private data for author.

3.Implement 2 subclasses of WrittenItem: Book and JournalPaper.

3.1.Class Book: no newprivate data. When needed, override/overload methods from the superclass.

3.2.Class JournalPaper: addedprivate data for year published. When needed, override/overload methods fromthe superclass.

4.Implement another abstract subclass of Item named MediaItem anddefine all common operations on this class. Added private data for runtime (integer).

5.Implement 2 subclasses of MediaItem: Video and CD.

5.1.Class Video: addedprivate data for director, genre and year released. When needed,override/overload methods from the superclass.

5.2.Class CD: added privatedata for artist and genre. When needed, override/overload methods from thesuperclass.

Write the definitions of these classes and a client program(your choice!) showing them in use. Some possible output could look like this:
