Question

Must be done in C#

Rare Collection. We can make arrays of custom objects just like we’ve
done with ints and strings. While it’s possible to make both 1D and 2D arrays of objects
(and more), for this assignment we’ll start you out with just one dimensional arrays.
Your parents have asked you to develop a program to help them organize the collection
of rare CDs they currently have sitting in their car’s glove box. To do this, you will first
create an AudioCD class. It should have the following private attributes.
 String cdTitle
 String[4] artists
 int releaseYear
 String genre
 float condition
Your class should also have the following methods:
 Default Constructor: Initializes the five attributes to the following default values:
◦ cdTitle = “”
◦ artists = {“”, “”, “”, “”}
◦ releaseYear = 1980
◦ genre = “”
◦ condition = 0.0
 Overloaded Constructor: Initializes the five attributes based on values passed
into the formal parameters
◦ If condition is less than 0.0 or greater than 5.0, set it equal to 0.0
◦ If releaseYear is less than 1980, set it equal to 1980
◦ Print message if the parameter’s artist array size is greater than 4, and only
store the first four values
 Getter method for all class attributes
You will then create a separate class, Assignment7A. In its main method, you should
do the following:
 Ask the user how many Audio CDs are in their collection
 Create an array (of type AudioCD) of that size
 Use a loop to ask the user to enter information for all CDs
◦ Create a AudioCD object for each Audio CD and store it in the next index in
the array
Then using another loop, you should give the user the following options:
 Print Audio CD information
◦ This should ask the user for a number, and then print the information from the
AudioCD object at that index using a custom toString() method. If the index is
out of bounds, it should notify the user instead.
 Search for an Audio CD from the collection
◦ This should ask the user for an Audio CD name, then search the array for an
Audio CD with that name (case insensitive). If it exists in the array, then it
should print the same information about the Audio CD as in the prior point
(Hint: Could you make a method to simplify this process?). If it does not exist
in the array, notify the user.
 Search for an artist from the collection
◦ This should ask the user for an artist name, then search the array for an
Audio CD by that artist (case insensitive). Print all the Audio CDs that the
artist worked on in the collection. If they are not in the array, notify the user.
 Quit
◦ Ends the loop and the program
