- a. Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).Design a Book class that holds the title, author’s name, and price of the book. Books’s constructor should initialize all of these data members except the price which is set to 500/-. Create a display method that displays all fields. All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces the Bookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the display method to display all fields. Write a Main () method that declares an array of five Book objects. Ask the user to enter the title and author 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. c sharpDesign a GUI for Book view class for the following Library Information System, which you have worked on 1 with the following details: Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program that creates three instances/objects of the Library Items class. Extending Library Item Class (Library and Book Classes): Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program with an object of Book class.

You are not limited to the features included in these instructionsDesign the Club class, to be used in your application, containing: A private data member code of type string that holds the three letters club’s abbreviation(ex, FCB, LIV, RAM ...) A private data member name of type string that holds the club’s name (ex, FC Barcelona,Liverpool, Real Madrid …) A private data member round of type integer that holds the number of rounds the club hasplayed so far in the current league. A private data member wins of type integer that holds the number of times the club haswon in the current league. A private data member draws of type integer that holds the number of times the club hasbeen drawn in the current league. A private data member losses of type integer that holds the number of times the club haslost in the current league. A private data member goals of type integer that holds the…Create a class Car which contains members speed, noOfGear. The class has a method drive( ) which is responsible to provide starting speed and noOfGears to a Car. Implement display( ) method which will display all attributes of Car class. The class SportCar is derived from the class Car which adds new features AirBallonType. When this method is invoked, initial speed and gear status must be displayed on console. Override the display method which display all attribute of the SportCar. Make use of super class display( ) method.Create a class Course to describe a course according to the following requirements: A course has three attributes: courseName, courseCode, fees. Create a constructor without parameters to initialize all the instance variables to default values (0 for numbers and "" for a string). Create a constructor to initialize all the attributes to specific values. Add all setter and getter methods Create a tester class with the main method. The tester class must be named using your first and last In this class performs the following: Create a course object c1 using the default constructor. Create a course object c2 with the following information: courseName =” object oriented programing”, courseCode = “CS230” , fees = a value from your choice. Change the course fees of c2 to your age. Print the course information of c2 using getter methods I attached Typical run of the program
- Design a class named TermPaper that holds an author's name, the subject of the paper, and an assigned letter grade. Include methods to set the values for each data field and display the values for each data field. Create the class diagram and write the pseudocode that defines the class.Create a class for Subject containing the Name of the subject and score of the subject. There should be following methods: set: it will take two arguments name and score, and set the values of the attributes. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. set: it will take one double value as argument and set the value of score only. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. display: it will display the name and score of the subject. Like “Name : Math, Score: 99.9” getScore: it will return the value of score. greaterThan: it will take subject’s object as argument, compare the calling object’s score with argument object’s score and return true if the calling object has greater score.
