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:

How do you use parametric polymorphism in a subprogram, and can you give an example?
Use java programming properties to write all the necessary classes and/or interfaces for a solution to the problem. Focus on class structure and interaction. You may implement your solution however you wish, but you will be graded on the appropriateness of your solution to the requirements. Note the use of capitalization and parentheses for clarification. You may use whatever constructors or additional methods you wish. Define a structure that can represent Animals. Animals have two behaviors; they can speak() and they can move(). By default, when an animal moves, the text ”This animal moves forward” is displayed. By default, when an animal speaks, the text ”This animal speaks” is displayed. A general Animal should not be able to be instantiated. Define two classes, Goose and Lynx, that are Animals. Both Goose and Lynx behave such that where “Animals” is displayed in speak() or move(), “goose” or “lynx” is displayed by the appropriate classes. Finally, any instance of Goose can fly(),…

Write program in C++ using inhertiance and polymorphism. A car dealership wants you to keep track of their sold and leased vehicles. You have realized that all vehicles have a make, model and vehicle identification number so you are going to factor those attributes out and put them in the base class as private attributes. Additionally you realize that you need to create two derived classes: one that keeps track of vehicles that are sold and the other that keeps track of ones that are leased. Vehicles that are sold have a sale date and sale amount. Vehicles that are leased have a monthly lease payment and terms of the lease (number of years). For all classes, create a proper overloaded constructor and display method that properly displays the class’s attributes. For your display method make sure you are using proper run-time polymorphism techniques so that your code calls the correct display methods.
