In Java. Screenshot explains. Implement the Shape hierarchy -- create an abstract class called Shape, which will be the parent class to TwoDimensionalShape and ThreeDimensionalShape. The classes Circle, Square, and Triangle should inherit from TwoDimensionalShape, while Sphere, Cube, and Tetrahedron should inherit from ThreeDimensionalShape.Each TwoDimensionalShape should have the methods getArea() and getPerimeter(), which calculate the area and perimeter of the shape, respectively. Every ThreeDimensionalShape should have the methods getArea() and getVolume(), which respectively calculate the surface area and volume of the shape. Every class should have a member variable containing its dimensions -- for example, the Circle class should have a member variable describing its radius, while the Triangle class should have three member variables describing the length of each side. Note that the Tetrahedron cass should describe a regular tetrahedron, and as such, should only have one member…
1: create a class Pentagon, which implements the RegularPolygon interface. It should have a double field called length, as well as a constructor that initializes this length field to a given value. 2: In the main() method of Pentagon class, add the following code: RegularPolygon sq = new Square(10); RegularPolygon penta = new Pentagon(20); Write code to get the perimeter for sq and penta. 3: In the main() method defined in Q2, add this line of code: sq.getArea(); Will this code pass through compiler? What is the reason? The Java feature in Q1 which create a new version of predefined method getPerimeter() is called Polymorphism Override Overload Inheritance
We have to calculate the area of a rectangle, a square and a circle.Create an abstract class 'Shape' with 2 dimension fields and an abstractmethod namely 'area'. Now, write 3 classes ‘Rectangle', 'Circle' and‘Triangle’ derived from the ‘Shape’ class. Implement the area() methodas necessary in each class.Now create another class 'Geometry' containing the main method andcreate objects of 'Rectangle', 'Square' and 'Circle' and printing theirarea.
Need help developing the following in Java: Create an abstract class "Shape" with the following specifications: An abstract method "surface_area ()" of return type double An abstract method "volume()" of return type double Put your code in a Java source file named "Shape.java." I. Create a class "Sphere" that extends the Shape class with the following specifications: Attributes: Radius Constructor: Implement a parameterized constructor needed to initialize the data. toString: Implement a "toString" method that prints out the surface area and volume. Implement methods to compute the surface area and volume. II. Create a class "Cylinder" that extends the Shape class with the following specifications: Attributes: Radius, height - both of type double Constructor: Implement a parameterized constructor to initialize the data. toString: Implement a "toString" method that prints out the surface area and volume. Implement methods to compute the surface area and…
In this problem, we are going to use ArrayLists and classes to design a road trip. You have three classes: GeoLocation.java which represents a geo location. A RoadTrip.java class, which represents a road trip (or an ordered list of places), and a RoadTripTester.java class which brings them all together. In GeoLocation.java: Add a private instance variable called name which is a String. This represents the name of the location. Modify the Geolocation class constructor so that it is now of the format public GeoLocation(String name, double theLatitude, double theLongitude) Add a getter method for name called getName(). Update the toString so that it returns a String of the format San Francisco (37.7833, -122.4167) Now, you’ll also need to create a RoadTrip class. RoadTrip stores an ordered list of locations, so you’ll need to have an ArrayList as an instance variable. The RoadTrip class constructor should initialize an ArrayList that stores a list of GeoLocations. You’ll also need to…
a:) Define a Polygon interface that has methods area() and perimeter(). b:) Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. c:) Implement classes, IsoscelesTriangle, Equilateral-Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. d:) Write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then output their area and perimeter. e:) For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar. using all a to e parts develop a program
Java ProgramFollowing the example of the Circle class in Section 9.2, design a class named Rectangle to represent a rectangle. The class contains:- Two double data fields named width and height that specify the width and height of the rectangle. Thedefault values are 1 for both width and height.- A no-arg constructor that creates a default rectangle.- A constructor that creates a rectangle with the specified width and height.- A method named getArea() that returns the area of this rectangle.- A method named getPerimeter() that returns the perimeter Draw the UML diagram for the class then implement the class. Write a test program that creates two Rectangle objects—one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.
How would I create this using Java. Sample run attached in image. The goal of this is to create two classes BookstoreBook and LibraryBook that both extend the class Book. The class Book is to be made abstract and to have these private attributes: author: String tiltle: String isbn: String To the Book class, add the abstract method: public String getBookType(); - The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like .2 off...etc). For that, add double price, boolean onSale and double saleRate as private fields to the BookstoreBook class. Obviously, saleRate is 0.0 when onSale is false. - In the LibraryBook class, we add Subject and callNumber as String. The call number is automatically generated by the following procedure: The callNumber has the format S.XX.YYY.C, where S is the subject code. The list of subject codes is provided at the end of…
JAVA PLEASE Starting with your solution to the previous task, add the following methods to your ScaleneTriangle class to extend its functionality. A default (or "no-argument" or "no-arg") constructor that constructs a Triangle object using default values. An overloaded constructor that constructs a Triangle object with the given values. A method named getArea() which returns the area of a triangle. This method returns a double. The are is calculated by: √(s * (s - sideA) * (s - sideB) * (s - sideC)) where s = (sideA + sideB + sideC) / 2 Write the ScaleneTriangle class in the answer box below assuming that the superclass is given. For example: abstract class Triangle { protected double sideA; protected double sideB; protected double sideC; public Triangle() { sideA = sideB = sideC = 10; } public Triangle(double sideA, double sideB, double sideC) { this.sideA = sideA; this.sideB = sideB; this.sideC = sideC; } public double getSideA() { return sideA; } public…
solve this by arraylist in the last of the question it has been told Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also…
