Write a class called Book having the following data members: title (String), author1 (String), author2(String), publisher (String), yearPublication (int), isbn (String), accessionNum (long), issuedTo (LibMember). Include following public methods in the class: Default constructor (without any parameters), constructor with 6 parameters (except for issuedTo – initialize issuedTo to null), set and get methods for all attributes, equals and toString. NOTE: The ISBN is a unique 13 digit number assigned by the publisher. It is like barcode. As there can be multiple copies of a book in a library, the libraries assign a unique number, called accession number, to every book in the library to keep track of the books in the library. Assume that accession number starts from 1001.

Given this class, please add the requested methods in the designated spaces provided. Instance methods: a) Write two constructors that will initialize the instance variables for a Student instance as follows: 1) Write a constructor that takes in three parameters – an int, a String, and a double. The constructor will assign them to the ID, name, and GPA instance variables respectively. 2) Write a no-argument (zero-parameter) constructor that will set the ID to - 1, the name to “No name assigned”, and the GPA to –1.0. b) Write an accessor method for the name variable. c) Write a mutator method for the GPA variable. d) Write a toString() method that will display all three instance variables on a single line, with a | (vertical bar) character between each one. e) Write an equals() method that returns true only if all three instance variables are equal. public class Student { // declare instance variables here private int ID; private String name; private double GPA;

Make C# (Sharp): console project named MyPlayList. Create an Album class with 4 fields to keep track of title, artist, genre, and copies sold. Each field should have a get/set property. Your Album class should have a constructor to initialize the title (other 3 variables should default to null or 0). In addition, create a public method in the Album class to calculate amount sold for the album (copies sold * cost_of_album). You determine the cost of each album. Also create a method in the Album class to display the information. Print out of information should look something like this: The album Tattoo You by the Rolling Stones, a Rock group, made $25,000,000. In the main method, create 3 instances of the Album class with different albums, use setters to set values of the artist, genre, and copies sold. And then use getters to display information about each on the console.

in the date classOverload the constructor method as the class diagram showsIn the main program, create three objects of class date, one from each of the constructors.In the main program, overload the showdate method to display the date in the following formatsThe date in dd/mm/yy formatThe date in dd/mm formatThe date in “d of month” formatIn the main program, make use of each of the showdate methods, one with each of the created objects.Send your two files, the date file and the main program where you use the date constructor overload and the showdate method overload.
