- Create a class Animal Create a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal (String name) //constructor public void makes Sound () with the implementation printing out a generic animal sound. Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. (you should observe the makeSound method called will be: cat -> from Cat class, dog-> from Dog class, bearded Dragon -> from Animal class ) EC:…arrow_forwardThis assignment is about OOP: Given Human class (Human.java) , please write a Student class (Student.java).

A constructor for the class takes two values, one for the name and the other for the count, and stores the two values in the instance variables. The class must be comparable, with the declaration of implements Comparable<NameAndCount>. The class has a “getter” for the name, named getName, and a “getter” for the count, named count. For “setters”, there is a method named increment that increases the value of count by 1. There is another instance method equals, which receives a String data as its parameter, and returns a boolean value indicating whether or not the contents of the String data is equal to the contents of name. Additionally, the class must implement the compareTo method, which returns the result of comparing the values of count. please write java code for above question and please send me the screenshot of the output formatarrow_forward
- Python:Please read the following. The Game class The Game class brings together an instance of the GameBoard class, a list of Player objects who are playing the game, and an integer variable “n” indicating how many tokens must be aligned to win (as in the name “Connect N”). The game class has a constructor and two additional methods. The most complicated of these, play, is provided for you and should not be modified. However, you must implement the constructor and the add_player method. __init__(self,n,height,width) The Game constructor needs to initialize three instance variables. The first, self.n, simply holds the integer value “n” provided as a parameter. The second, self.board, should be a new instance of the GameBoard class (described below), built using the provided height and width as dimensions. The third, self.players, should be an initially empty list. add_player(self,name,symbol) The add_player method is provided a name string and a symbol string. These two values should be…arrow_forwardWrite a Java application for the Banking system that consists of at least three classes for Bank, Clients and Transactions.

For this assignment, we will be examining the Beverage2 class (an updated version of the Beverage class from discussion 1), its subclass Espresso, and the TestBeverage2 class. This time, assume that all source files are in the same package. Note that some lines may wrap, but are still considered on one line. Examine the code below. Recall that variables have four kinds of scope: static, instance, local, and block. For each variable listed below, identify its scope (static, instance, local, or block) and describe the scope using complete sentences. An example description is provided, after the code listing, for the ounces variable in the Beverage2 class. Please describe the scope for the following variables: The num variable in the Beverage2 class The price variable in the Beverage2 class The shots variable in the Espresso class The b variable in the TestBeverage2 class The j variable in the TestBeverage2 class public abstract…arrow_forward
- In Java: -Using a BST Interface (Binary Search Tree) -Create a class Disk. Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…arrow_forwardDoes every class have a copy constructor? How is a copy constructor named? Can it be overloaded? Can you redefine a copy constructor?
