Question: Write the Java code below in IDE ECLIPSE enviroment and provide screenshots of the execution.

Project Media Rental System Before attempting this project, be sure you have completed all of the reading assignments, non- graded exercises, examples, discussions, and assignments to date. Design and implement Java program as follows: 1) Media hierarchy: Create Media, EBook, MovieDVD, and MusicCD classes from Week 3 -> Practice Exercise - Inheritance solution. Add an attribute to Media class to store indication when media object is rented versus available. Add code to constructor and create get and set methods as appropriate. Add any additional constructors and methods needed to support the below functionality 2) Design and implement Manager class which (Hint: check out Week 8 Reading and Writing files example): stores a list of Media objects has functionality to load Media objects from files creates/updates Media files has functionality to add new Media object to its Media list has functionality to find all media objects for a specific title and returns that list has functionality to rent Media based on id (updates rental status on media, updates file, returns rental fee) 3) Design and implement MediaRentalSystem which has the following functionality: user interface which is either menu driven through console commands or GUI buttons or menus. Look at the bottom of this project file for sample look and feel. (Hint: for command-driven menu check out Week 2: Practice Exercise - EncapsulationPlus and for GUI check out Week 8: Files in GUI example) selection to load Media files from a given directory (user supplies directory) selection to find a media object for a specific title value (user supplies title and should display to user the media information once it finds it - should find all media with that title) selection to rent a media object based on its id value (user supplies id and should display rental fee value to the user) selection to exit program 4) Program should throw and catch Java built-in and user-defined exceptions as appropriate 5) Your classes must be coded with correct encapsulation: private/protected attributes, get methods, and set methods and value validation 6) There should be appropriate polymorphism: overloading, overriding methods, and dynamic binding 7) Program should take advantage of the inheritance properties as appropriate
