OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Look at the following class definition. What is the name of the superclass? What is the name of the subclass? class Tiger(Felis): True or FalseLooking at the following class definition. What is the name of the superclass? What is the name of the subclass? class Rectangle(BBox):You have a method which requires an argument of type superclass. It will function if you supply a subclass object rather than a superclass object. Is it permissible? What is the purpose?
- You have a method that takes an argument of type superclass object. You may make it function by providing an object of a subclass rather than a superclass. Is that allowed? I don't see the purpose.What is the superclass and what is the subclass in the following line? public class Pet extends DogLook at the following code, which is the first line of a class definition. What is the name ofthe superclass? What is the name of the subclass?class Canary(Bird):
- Declare a superclass and subclass. Override a method of superclass in subclass and call thesuperclass’s constructor from the subclass with proper java syntax.Java - If the programmer doesn't declare any constructors for an extended class, what constructors will be inherited from the superclass? How does this inherited constructor initialize new instance variables that are not part of the superclass?Write the abstract super class Transaction, and two of its subclasses, Payment and Sale (you do not need to supply any comments other than your name). I. Write an abstract superclass encapsulating a Transaction: The Transaction super class has an instance variable representing the customers name, and 3 methods: an overloaded constructor, a toString() method that returns a message including the name of the customer, and an abstract method called calculateAmount()which will be implemented in your subclasses. II. Write a non-abstract subclass that inherits from the Transaction class encapsulating a Payment: The Payment class has instance variable representing the payment amount received and 3 methods. It has an overloaded constructor, a toString() method that returns a message including customers name, the name of the class Payment, and the payment amount, an non-abstract class called calculateAmount() which returns the payment amount. III. Write a second…
- You have a method that requires an argument that is an instance of the superclass, and it expects you to provide it. It will function properly if you provide it with an object of a subclass rather than a superclass. Is it even possible? Where is the value in that?Assume you have a method that requires the superclass's object as an argument. If you offer it a subclass object rather than a superclass object in this scenario. Is it appropriate? Why do you think that is?What keyword is used if a subclass needs to call a method in a superclass?
