in C# languageDesign a Book class that holds the title, author’s name, and price of the book. Books’s constructor shouldinitialize all of these data members except the price which is set to 500/-. Create a display method thatdisplays all fields.All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces theBookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the displaymethod to display all fields.Write a Main () method that declares an array of five Book objects. Ask the user to enter the title andauthor for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following:Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details.

Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field.  setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field.  getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required).  getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )]  getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…

Objectives: At the end of this activity, you should be able to: define classes implement polymorphism and inheritance instantiate an object array apply Exception to all input validations create a Java application for multiple users Procedure: Create a NetBeans project for this activity. The project name should be as follows: o Client (the main class that contains the main method and the implementation of the main menu) o Credit (the class where attributes and methods are defined) The class names to be created are the following: o Client<your_last_name> Ex. ClientBlancoo Credit<your_last_name> Ex. CreditBlanco All class names must be suffixed with your last name. Note that the object to be instantiated in the main method is an object array.For example: CreditBlanco [ ] cb = new CreditBlanco [100]; Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS. Only NetBeans project compressed in .rar or .zip format will be…

Practice with writing a program that contains three classes: Ship CruiseShip CargoShip Classes Design a Ship class with the following members: A field for the name of the ship (a string) A field for the year that the ship was built (a string) A constructor that accepts two arguments for the two fields, and appropriate accessors and mutators A toString method that returns a string with the ship’s name and the year it was built Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CruiseShip class’s toString method should return a string with only the ship’s name and the maximum number of passengers. Design a CargoShip class that extends the Ship class. The CargoShip class should have the…
