- *using java* Create a class AnimalCreate 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 makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()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 implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…Encircle/ write down the correct/missing code.Elaborate if needed by writing a comment. //this is a subclass of superclass Teacher public class ScienceTeacher { Public final boolean ScienceMajor; Science (String ScienceMajor, String name, String age){ this.ScienceMajor= ScienceMajor; super(name, age); } }If A and B are reference variables to the objects of MyClass, what can we say aboutthis comparison? (Pick all true statements.)if (A.equals(B)) {...} A. It is identity test.B. It checks whether two objects are equal if the equals method is overridden in MyClass.C. None is correct.D. It checks whether both are referring to the same object if the equals method is not overriddenin MyClass.
- Create a parent class Person with one attribute age and one method greet() that prints out "Hello, world!". By default, the age is 20. Then create a subclass CollegeStudent that inherits from Person and has its own attributes School_Name and Major. Then create an object (a college student, his name is Harry, age is 21, School_Name is "Felician University", and Major is "Computer Science"), then let Harry say"Hello World!".Write a Java class Student inherited from Person class. Your class must have the following features: Student - major: String + Student() + Student(name: String, id: int, major: String) + getMajor(): String + Override toString() method: you have to return needed data Fields values. Note: major data members can take only CS for Computer Science, CIS for Computer and Information Systems, CPE for Computer Engineering, SE for Software Engineering, and NES for Network Engineering and Security.In Java: Implementing a Superclass Employee Part 1: Implement a superclass Employee that has the following fields and methods. Fields: string firstName string lastName int employeeID double salary Methods: constructor method - initialize salary field to zero. setters and getters for firstName, lastName, and employeeID employee Summary method - prints all account attributes Part 2: Implement a Manager class that inherits from the Employee class. Fields: string department a Methods: employeeSummary method - prints all superclass and subclass attributes Ensure that your program has the two required classes and a test class.
- Write a java program that Create a generic class AnimalList that has a type parameter T. It should have at least two properties declared as the passed type, constructors), getters, setters, and toString methods. Create a superclass Animal that has two properties (String, int, etc.), and constructor, getters, setters, and toString methods. Create two subclasses of Animal called Cat and Dog. Each class should have a unique property and method. Create a class Lizard with a method of your choice. Create a main class AnimalTest that creates two instances of Animal: Dog type and Cat type. Create a method that takes Animal type as parameter constraining the types to be subclasses of the Animal class only; check the type of object and call the unique method in the Dog and Cat. Create an instance of the Lizard class and test it. Display all objects.The xxx_Pet classA Pet has a:– Name• Include an instance variable• Getters and setters for an instance variable• A toString method which returns a String containing the pet name Abstract methods: speak() and move()The subclassesWrite a dog, cat, snake subclasses with proper instant variables and methodsWrite a class xxx_TestPet which will1- Create a dog, a snake, and a cat objectsSample OutputPet Fido is a dog, weighing 45 poundsFido says woofrun Fido runPet Sam is a snake, 30 inches longSam says hissslither Sam slitherPet Hershey is a cat, with Long hairHershey says Meowprance Hershey prance2- Print just the weight of the Dog, the length of the Snake and the hair length of theCat as shown belowFido weighs 45 poundsSam has length 30 inchesHershey has Long hair 3- Store the objects in an Array of Pet objects and print the information belowPet D1 is a dog, weighing 55 poundswoofrunPet S1 is a snake, 30 inches longhissslitherPet C1 is a cat, with Long hairmeowprancePet D2 is a dog,…Please answer in python Before we start looking at some of the more interesting methods for Crew and its subclasses, we need a class to represent the spaceship that the crew members are interacting with. For now, we’ll just set up the constructor for the Starship class. Constructor: The Starship class constructor should have the following signature: __init__(self, name, crew_list) Where name (the name of the ship) is a string, and crew_list is a list of the Crew objects (or its subclasses) that make up the crew of the ship. The constructor should create instance variables to store the value of the arguments (self.name and self.crew_list respectively), along with one more instance variable: self.damaged, a dictionary with string keys and boolean values representing whether each area of the ship is currently damaged. This should be initialized to: {'Bridge':False, 'Medbay':False, 'Engine':False, 'Lasers':False, 'Sleep Pods':False} Examples: Copy the following if __name__ ==…

Getters for each attribute. add_course(course: String, grade: Integer) : Bool -- This operation adds the course name to the list of courses and the grade to the list of grades. The method must confirm before adding that the course is a String and the grade is an Integer, otherwise the operation won't be performed. The method must return True if the course and grades were added, False otherwise. __str__() -- Should return the following information "Student name: <name> -- Courses passed: <number of courses passed>". Courses passed means courses with a grade equal to 60 or larger. Check the testcase for details. pass_ratio(): Float -- Returns the pass ratio as a percentage of…Write a Java class Person for dealing with persons. Your class must have the following features: Person id: long name: String gender: String + Person() + Person (id: long, name: String, gender: String) + Create setter and getter for all data fields. + Override toString() method: you have to return required data Fields values. Constructor: public Person(): A default constructor, should initialize the data fields to their default values. public Person (SSN: long, name: String, gender: String): A constructor with parameters, that creates the person object by setting specified parameters.
