- 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:…Class student inherits from superclass Person.

- Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.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.Answer the given question with a proper explanation and step-by-step solution. The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.
- Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle.

To call a method in Parent from Child, we use: a) super b) private c) public d) protectedPLZ help with the following IN JAVA When defining an inner class to be a helper class for an outer class, the inner classes access should be marked as: Public Private Protected Package access
