Implement constructors for each of the three subclasses. Each constructor should call the superclass constructor to set the name. Here is one example: public IDCard(String n, String id) { super(n); idNumber = id; }

Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…
Consider the following class hierarchy: class Animal { ... } class Mammal extends Animal { ... } class Cat extends Mammal { ... } Write a generic method printArray that takes an array of any type and prints each element of the array. If the element is an instance of Animal or its subclass, the method should call the toString method of the object to print its details. Otherwise, the method should simply print the element. Your method should have the following signature: public static <T> void printArray(T[] array)
Goal 1: Update the Fractions Class ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer. For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class Add a private member variable of type int to denote the serving size and initialize it to 1. Update the overloaded extraction operator (<<) to include the serving size. New Member functions to the Recipe Class: 1. Add four member functions get the value of each of the member variable of the Recipe class: getRecipeName(), getIngredientNames(), getIngredientQuantities(), getServingSize() They return the value of the respective member variables. 2. Add and implement a member function that scales the current recipe to a new serving size. The signature of this function is: void scaleRecipe(int…
Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.
c++ Declare an Animal class that has the attributes of Name, Genus, and Weight. Declare four (4) specific animal classes that inherit attributes from the Animal class. In the lab we built two, Duck and Butterfly. Implement show() and speak() methods for each subclass. These methods will also be virtual classes in Animal and will allow the use of an array of Animal* in the main(). Your program should ask the user for the number of animals they would like in there zoo. Allow the user to select each animal from the animal subclasses you have implemented. Store the selections in an array of Animal*. After the user has selected all the animals, step thru the array and have each animal show() and speak() in a sort of parade of selected animals. I'm having a problem with the error message and why it won't display to ascii art and have the user input --- This is my code so far --- /* * File: Zoo.cpp * Author: * Course: CS I * Assignment: What's In Your Zoo? * Due date: 11/10/21 * *…
Given below is a UML diagram for address class. Address -Street: String -City: String -State: String -Postal code: String -country: String +methods a) Write the code for default constructor and set the values of the data fields to null? b) Write the code for overloaded constructor with formal parameters and set the values of the data fields to the parameter listing. c) Write the code for mutator and accessor methods.
Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
Design a console program that will print details of prescribed textbooks of students. Make use of an abstract class Book with variables that will store the author, title, category and price of a book. Create a constructor that accepts the author, title and category through parameters and assign these to the class variables. Create an abstract set method for the price of a book; also create get methods for the variables.Create a subclass TextBook that extends the Book class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String DisplayDetails();}The TextBook subclass has a private variable named yearPrescribed for which a get method must be written. The constructor of the TextBook class must accept the author, title, category and yearPrescribed through parameters. Write the code for the setPrice() and DisplayDetails() methods.Write a useBook class and instantiate 2 objects of the TextBook class.
Course Title: Modern Programming Language Please Java Language Code Question : Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design Rectangle18-ARID-2891 and CircleM.JibranAkram Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length
The class diagram below shows an Order class that "has a" Customer and zero or more Items. Order class should contain private Customer m_cust; private ArrayList<Item> m_items; public Order(Customer cus t) public void additem(Item i) public String toString() Item class should contain private String m_desc private int m_qty private double m_price public Item(String des c, double price, int qty) public String toString() Customer class should contain private String m_first; private String m_last; public Customer(String first, String last) public String toString() Please create the Order, Customer, and Item classes shown above. I have provided you with a read-only Main class that you can use to test your code. When you have completed the Order, Customer, and Item classes, running the Main program should produce the following output: Order for Smith, Tom Order Items: Greeting Card: 1 at 1.5 Baseball Glove: 1 at 54.0 Notebook: 3 at 2.5 public class Main{ public static void…
Subtask I: You will implement two classes Bid and Auction. The details are as follows: To keep things simple, each bid contains 3 attributes: bid_id: the identifer for this bid; • bidder_id: the identifer of this bidder; and auction: the identifer of this auction. ● Notice that bid_id is a unique identifier (think of a ticket) used to identify a bid whereas bidder_id identifies the person who made this made. Details about your Bid class: Your Bid class • can be instantiated via Bid (bid_id, bidder_id, auction), for example, bidtest = Bid(1, '8dac2b', 'ewmzr') provides the following access to data: If b is a Bid instance, then b. bid_id, b. bidder_id, and b. auction store this bid's bid_id, bidder_id, and auction, respectively. • has appropriate __str__ and __repr__ methods that show this bid's information. We do not specify the format. supports comparison using , ,==: two bids are compared exclusively by their bid_id. As an example, a bid with bid_id 3 is (strictly) smaller than a bid…
