Given a base class with the following UML class diagram. Create a Person base class for thefollowing. You have to create a NetBeans project for this question.Person- name: String+ setName(String newname): void+ getName( ): String+ writeOutput ( ): void+ equals (Person otherPerson): booleanYou have to use the base class Person you have created to derive a class named as Studentthat can be used for the objects for students in a university. The employee record will inherita student's name from the class person. A student record will contain the GPA scorerepresented as a single value of type double, a starting date that gives the year that studentstarted the course as a single value of type int, and a student identification number that is avalue of type long.You have to provide your solution with the following guidelines.• Provide the Person Base Class (2 marks)• You have to provide the derived Student class from Person class and take care of thefollowing.• Provide appropriate private instance variables for the information required in thederived class. (2 marks)• Explain and demonstrate the importance of using private instance variables. (2marks)• Provide a default constructor and all other necessary constructors required for thederived class. (2 marks)• Provide all necessary mutator and accessor methods in the derived class. (2 marks)• Provide a writeOutput and equals methods in the class Student. (2 marks)Using the class Student that you have created to explain the differences betweenoverloading and overriding methods using the methods in class Person and classStudent. (2 marks)• Using the class Person and class Student, explain what is polymorphism and providean example of how you can use the two classes to illustrate the concepts ofpolymorphism. Note: if you just provide definition of polymorphism without usingcode and example for the classes to explain, you will receive 0 mark for this part. (4marks)Provide a client class such that you can demonstrate the use of the derived Studentclass and for testing purposes. (2 marks)NOTE: If your project file cannot be run, you will only receive 50% of the marks of thisquestion. Test it before submission.Remember to submit your NetBeans Project file.

Here, for solving the particular case, I have attached the whole requirement i.e., the java code and…

Suppose you are working on a project managing the bus fare of Dhaka metropolitan city. At this point you are designing a vehicle class(choose if you need to define it as an abstract class, interface or concrete class). After that, you need to create different classes such as Bus, Double_Decker_Bus, Mini_Bus, Regular_Bus and all of these classes will extend the Bus class. You are free to define the classes as you deem necessary. In the driver class, you must be able to call methods to print the bus fare per kilometer for double_decker bus, regular bus and mini bus(the fare should be different). You also need to calculate the bus fare of a route based on user input(in kilometers) to display the total bus fare for a single person. Adding to this, you will be able to calculate student fare based on the availability of the student ID card.
Consider an example of declaring the examination result. Design three classes:Student, Exam and Result. The Student class has data members such as thoserepresenting roll number, name etc. create a class Exam by inheriting the student class.The exam class adds data members representing the marks scored in six subjects.Derive class Result from the exam class and it has own data members such as total_marks. Write an interactive program to model this relationship. What type ofinheritance this model belongs to?

In C++ Create a new project named lab8_1. You will be implementing two classes: A Book class, and a Bookshelf class. The Bookshelf has a Book object (actually 3 of them). You will be able to choose what Book to place in each Bookshelf. Here are their UML diagrams Book class UML Book - author : string- title : string- id : int- count : static int + Book()+ Book(string, string)+ setAuthor(string) : void+ setTitle(string) : void+ print() : void+ setID() : void And the Bookshelf class UML Bookshelf - book1 : Book- book2 : Book- book3 : Book + Bookshelf()+ Bookshelf(Book, Book, Book)+ setBook1(Book) : void+ setBook2(Book) : void+ setBook3(Book) : void+ print() : void Some additional information: The Book class also has two constructors, which again offer the option of declaring a Book object with an author and title, or using the default constructor to set the author and title later, via the setters . The Book class will have a static member variable…

We are working in 2D and programming in C#. Create a Point class to represent points in 2D. Create an abstract base class named Shape. It should have a position property as a Point. It should be designed as having Move and Resize methods. Create a Line class using Points, derived from Shape class. Its position should be the center of the line. Create a Polygon class representing a closed polygon of Lines, derived from Shape class. Note that, at construction time, Lines may not be provided in order. The continuity and number of the lines should also be checked for a properly closed Polygon. All geometric entities should be moveable. All shapes should be resizable without changing their central positions. All shapes' positions should be their centroids. Shapes should have areas calculated. Write an example C# Console code to demonstrate your program's abilities.
