Define a class called Diamond that is derived from either the class ShapeBasics (Listing 8.12) or the abstract class ShapeBase (Listing 8.19) A diamond has the same sort of top half as a Triangle object, and its bottom half is an inverted version of its top half. Define a utility class having public static methods, such as the method skipSpace and other methods that draw horizontal lines, big V’s, and inverted big V’s Recall that Self-Test

- Imagine a publishing company that markets both book and audiocassette versions of its works. I it markets both book and audiocassette versions of its works. create a class called publication that stores the title (a string) and price (type float) and date of a publication. Provide getters/setters and constructor also write an abstract method isOversize() .From this class derive two classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of the classes should have a getter/setters and constructors and provide definition to function called isOversize() to the book and tape classes. Let’s say that a book with more than 800 pages, or a tape with a playing time longer than 90 minutes (which would require two cassettes), is considered oversize. You can access this function from main() and display the string “Oversize” for oversize books and tapes when you display their other data. explain the working in your wordsarrow_forwardImplement the following using JAVA: a.Design a class named Person and its two subclasses named Student andEmployee. b.Make Faculty and Staff subclasses of Employee. Please note that,● A person has a name, address, phone number, and email address. A student has aclass status (freshman,sophomore, junior, or senior). You can define the status as aconstant.● An employee has office & salary.● A faculty member has office hours and a rank.● A staff member has a title. c. Draw a UML diagram of the system.arrow_forward5. Given the Java Point class (which contains two private variables x and y and constructors that allows creating a point object with known x and y values as well as other methods such as equals( ), toString( ) etc), (a). define a new class called Circle that contains private two variables: center which is a Point object from the Point class and radius which is of type double. The Circle class must have the following methods: (b). add a constructor which creates a circle object using a center point with x and y values and a radius as its parameters. (c). add a default constructor. ( (d). add an equals() method that can compare if any object is equal to a Circle object (two circle objects are equal if they have the same center point with the same radius). (e). add a toString() method that prints a Circle object with the center point and radius.arrow_forward
- Design and implement a class called Car that contains instance data that represents the make, model, and year of the car (as a String, String and int value respectively). Define the Car constructor to initialize these values (in that order). Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car of the form make-model (year)for example:Ford-Thunderbird (1955)arrow_forwardWrite a java program Write a class named Employee with name and salary as private data fields. Add a constructor with both parameters. Write a class named Manager which unherits the Employee class. Add an instance variable, named department, of type String and 15 private. Add a constructor in the subclass class and a toString () method that prints the manager's name, department, and salary [Hint: Add a tastanel) method in the super class as well]. Create objects of Manager and Employee dassarrow_forward16. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.)arrow_forward
- 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.arrow_forwardMake a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type string. Supply a method tostring that prints the manager's name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate tostring methods for all classes. Supply a test program that tests these classes and methods.arrow_forwardNeed help on java homework assignment, It says Create a class Vehicle. A Vehicle has a single instance variable of type String named "vehicleType" that describes the vehicle. It has an abstract method getTires that takes no parameters and returns an ArrayList<Tire> object that describes each Tire of the vehicle. A Tire class has been provided. Vehicle has a single constructor that takes the vehicle type as a parameter.Create a class Bicycle that extends Vehicle that has two Tires, both of type "skinny". Bicycle should have a single default constructor.Create a class Dragster that extends Vehicle and has four Tires, two of type "slick" and two of type "medium". Dragster should have a single default constructor.Write a tester program to test Bicycle and Dragster objects. Use declarations such as Vehicle b = new Bicycle();in your tester. Here is the code provided : public class Tire { private String size; public Tire(String siz) { size = siz; } public String…arrow_forward
- JAVA Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. Refers to this : Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0arrow_forwardCreate a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…arrow_forwardSOLVE IN C# Define a class Shape with an abstract method CalculateArea(). Define two additional classes for a triangle and a rectangle with fields width and height (values being set through appropriate constructors), which implement CalculateArea(). This method has to return the areas of the rectangle (height*width) and the triangle (height*width/2). Define another class for a circle with an appropriate constructor, which initializes the two fields (height and width) with the same value (the radius) and implement the abstract method for calculating the area. Create an array of different shapes and calculate the area of each shape in another array. helparrow_forward
