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:

Develop a program (or find one on the internet) to exemplify and document dynamic binding). A parent and two or more child classes are needed. Shape, Triangle, Rectangle are common examples where Shape is the parent and Triangle and Rectangle are the child classes. Create a project for the program, add the parent and childs classes to it. Use main to exemplify dynamic binding by creating an array or ArrayList of the parent class type and filling it with objects of the child class types. Loop through the array and display all the objects in it by calling their toString method. Then create a method whose parameter is the parent class type. Have main call the method sending it the child types. What the method does is up to you. Heavily document this program since this is not a prescribed assignment. I want to read your words. So I want you telling me what it does, how it does it, and how it has anything to do with dynamic binding. Then using screen capture software, take…

Assume we have a Book class that includes authorInit and pubYear attributes of type Stringand int, respectively, both set by the constructor. Write a compareTo method for this class, so thatbook objects are ordered based on the author’s initials first and then (if needed) the publication year. DO NOT assume the length of String type authorInit to be 2.
For this assignment, your implementation plan must include at least one class with public and private sections. For assistance with classes, see sections 6.2, "Using a Class," and 6.3, "Defining a Class," in zyBooks. For this assignment, we recommend using Maps (section 11.4 in zyBooks) for implementation. Maps do require precise coding syntax. However, you can choose a different implementation option. Apply industry standard best practices such as in-line comments and appropriate naming conventions to enhance readability and maintainability. Remember that you must demonstrate industry standard best practices in all your code to ensure clarity, consistency, and efficiency. This includes the following: Inserting in-line comments to denote your changes and briefly describe the functionality of the code Using appropriate variable, parameter, and other naming conventions throughout your code Optional Challenge: User Input ValidationValidating user input is a coding best…
