Shapes2D

Write the following four classes to practice using an abstract class and polymorphism. Submit all four classes.

Shape2D class

For this class, include just an abstract method name get2DArea() that returns a double.

Rectangle2D class

Make this class inherit from the Shape2D class. Have it store a length and a width as fields. Provide a constructor that takes two double arguments and uses them to set the fields. Note, the area of a rectangle is the length times the width.

Rectangle2D class

Also make this class inherit from the Shape2D class. Have it store a radius as a field. Provide a constructor that takes a double argument and uses it to set the field. Note, the area of a circle is PI times it's radius times it's radius.

Shape2DDriver class

Have this class provide a method named displayName() that takes an object from just any of the above three classes (you can't use an Object type parameter). Have the method display the area of the object, rounded to one decimal place.

I am writing a reasearch paper for my Accounting for Not-For-Profit Organizations class about higher education at public colleges and universities. I wrote an abstract for my paper. Enclosed is an my abstract and will you check and see if I need corrections? I don't mind if you get assistance from a person with an expertise in writing.

Abstract

For high graduates, it should be an exciting time for them with plans to go to college but it can turn out to be nightmare for both the students and their parents. The correlation between public universities raising tuition fees and potential students of diverse backgrounds wanting to attend their schools is on account of the following: a) Often, the students and parents equate price with equality. The parents feel that if they can’t afford that much price, they might be less attractive to students. b) Parents and students feel higher the tuition fees, higher the earning opportunities in future when college is done. c) Demand for higher education has grown across the globe. Jobs offered today are demanding higher education degree as a recruitment requirement. d) Every country might not have higher education levels. Thus, students prefer to travel to those countries which have higher education levels and thus willing to pay for the increased tuition fees. e) Rise is tuition fees is on account of inflation, though major universities have increased the tuition fees, the net price which is tuition fees - scholarships and other grants has not increased in real dollar terms for public universities. Thus, the rate of students opting for such colleges is still high.

ABSTRACT

The field of Engineering Systems is distinguished from traditional engineering design in part by the issues it brings to the top. Engineering Systems focuses on abstractions like architecture and complexity, and defines system boundaries very broadly. It also seeks to apply these concepts to the process of creating systems. This paper summarizes the role and influence of architecture in complex engineering systems. Using the research literature and examples, this paper defines architecture, argues for its importance as a determinant of system behavior, and reviews its ability to help us understand and manage the design, operation, and behaviors of complex engineering systems.

A. INTRODUCTION

Typical engineering design education focuses on specific aspects of design, such as the technical behavior of a set of elements interconnected in a certain way. By contrast, Engineering Systems focuses on a number of abstract concepts first because they provide a general framework for guiding the development of many diverse kinds of systems, so that these systems will provide the desired functions in the desired ways. Among these abstract concepts is that of system architecture. In this paper, we explore this concept and provide a number of ways of appreciating system architecture

which question is incomplete these question given like they are and i have to answer them. These are Java questions.

Q1. //Write an iterative method to count long book in the linked list. Assume that book has               method

// Boolean isLong () that returns true if book is long and returns false otherwise.

Public int countLongBooks ()

{

Q2. //Recursive method to add a new node (with myBook as data) at the rear of the list

Public void addToRearRec(Book myBook, Node first)

Q3. //Recursive method returns longest Book in the non-empty linked list. First refers to the first node in the linked l

// list.

    Public Book longestBook ( Node first)

{
