Write an java inheritance hierarchy for classes Quadrilateral, Trapezoid, Parallelogram, Rectangle and Square. Use Quadrilateral as the superclass of the hierarchy. Make the hierarchy as deep (i.e., as many levels) as possible. Specify the instance variables and methods for each class. The private instance variables of Quadrilateral should be the x-y coordinate pairs for the four end- points of the Quadrilateral. Write a program that instantiates objects of your classes and outputs each object’s area (except Quadrilateral).

- In Java Your uncle is trying to keep track of his new-car and used-car lots by writing a Java program. Heneeds your help in setting up his classes.Implement a superclass named Car that contains a price instance variable, a getPrice method, anda 1-parameter constructor. The getPrice method is a simple accessor method that returns the priceinstance variable’s value. The 1-parameter constructor receives a cost parameter and assigns avalue to the price instance variable based on this formula:price = cost * 2;Implement two classes named NewCar and UsedCar; they are both derived from the Carsuperclass. NewCar should contain a color instance variable (the car’s color). UsedCar shouldcontain a mileage instance variable (the car’s odometer reading). The NewCar and UsedCarclasses should each contain a 2-parameter constructor, an equals method, and a toString() method.In the interest of elegance and maintainability, don’t forget to have your subclass constructors callyour superclass constructors…Java - Polymorphism Create a class named “Shape” that has the abstract methods getArea() and getPerimeter(). Create classes named “Rectangle”, “Square”, and “Circle”. Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. For rectangle, create attribute length and width. For square, side. For circle, radius. Inputs 1. Char input for Shape type (R/S/C) 2. Dimensions of specific type of Shape C 5 Sample Output Shape(R/S/C): R Length: 10 Width: 50 Area: 500.00 Perimeter: 120.00Your assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…
- Java programing ShipsStudy the UML diagram carefully. The green spots signify public. The red squares signify private. Superclass Ship is abstract because it contains the abstract method purpose. This class also implements the Comparable interface to compare ships by tonnage. Ship also has a public static integer named numShips that is incremented in the constructor to serve as a counter for the number of ships.After coding these classes, write a program named TestShips that uses them as follows:⦁ Create an array of declared type Ship that contains at least six ships (two of each concrete subclass). You can make up all of the values for the data members of each ship.⦁ The Strings returned by purpose() can be determined by viewing the Possible Output below.⦁ Process the array in an enhanced for loop to display for each ship:⦁ The actual type using the getClass() method inherited from class Object.⦁ The output of the toString() method.⦁ The value returned by the purpose()…Create a classstudent which includes parameters roll_no, name and address and consider as super class.Then create sub class test with parameters marl1, mark2, mark3 and mark4. Then create another sub class result with parameters total_marks, percentage and grade. Apply multi level inheritance. Here Student class is the super class for test class and test class is super class of resultclass. Implement a java application in which obtain the details roll_no, name, address, marl1, mark2, mark3 and mark4 from user side andthen print total_marks, percentage and grade.StudentàtestàresultJust the class diagramWrite an inheritance hierarchy for the classes quadrilateral, trapezoid, parallelogram, rectangle, and square. Use quadrilateral as the superclass of the hierarchy. Add as many levels as possible to the hierarchy. Specify instance variables and methods for each class. The private instance variables of quadrilateral must be the x,y coordinate pairs for the four endpoints of the quadrilateral. Write a program that creates object instances of your classes that prints the area of each object.
- Write the Talker interface, Animal abstract class, plus the Dog, Cat, Fish, and Radio classes for this Java Program. Talker.java - the interface Talker, which has just one void method called speak() Animal.java - the abstract class Animal, which stores an animal's name. (No abstract methods). It should contain 2 methods: a constructor with 1 argument (the name) a method getName() which returns the name. Dog.java - the class Dog, which extends Animal and implements Talker. It should contain 3 methods: a constructor with no arguments, giving the dog a default name of "Fido" a constructor with 1 argument (the name) a speak() method that prints "Woof" on the screen. Use @Override Cat.java - the class Cat, which extends Animal and implements Talker. It should contain just 2 methods: a constructor with 1 argument (the name) (no default name like dogs have) a speak() method that prints "Meow" on the screen. Use @Override Fish.java - the class Fish, which is an Animal that…Task: Implement a class ChessPiece with properties: color, isAlive, moveCount, and position (x, y coordinates). Define an abstract move method. Create a Tower subclass that overrides move for specific behavior. Instructions: ChessPiece Class: Properties: String color, boolean isAlive, int moveCount, Position position. Abstract Method: move(int x, int y). Position Class: Contains int x, int y. Tower Subclass: Extends ChessPiece. Overrides move for straight line movement. Deliverable: Source code for ChessPiece, Position, and Tower. Document class functionalities briefly.Using JAVA Language Consider a Billing class that implements an interface Payable having a method getTotalPaymentAmount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID, pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and MedicalTest class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPaymentAmount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay. After implementing these classes, you are required to do the following in the driver class: Create an ArrayList of…
