There are multiple geometric shapes available. a. You have to organize the maximum number of shapes into appropriate level of inheritance. For example, all the squares are quadrilateral, and all the quadrilateral shapes are 2D shapes, and all the 2D shapes are shapes, just like that create a shape hierarchy. b. Create a UML class diagram for all the shape hierarchy you created in step a. Your UML class diagram should represent all the structure of classes and the relationship between classes. c. Explain the four basic OOP concepts in context of above shape hierarchy and highlight the advantage of using each of these OOP concept.

You are asked to design a software system to track an automobile manufacturing line. You will need to track the following components (wheels, brakes, engines and cooling systems). What would be the relationship best suited to describe the relationship between these components and the car? O A. inheritance B. composition O C. association O D. aggregation O E. polymorphism
The world of shapes is much richer than the shapes included in the inheritance hierarchy of Fig. 11.3. Write down all the shapes you can think of—both two-dimensional and three-dimensional—and form them into a more complete Shape hierarchy with as many levels as possible. Your hierarchy should have the base-class Shape from which class TwoDimensionalShape and class ThreeDimensionalShape are derived. [Note: You do not need to write any code for this exercise.] We’ll use this hierarchy in the exercises to process a set of distinct shapes as objects of base-class Shape .
You are building a system for a Housing Society, such as Bahria Town. You are supposed to design a system that allows them to keep a record of how many blocks, sectors, streets, and houses the society has. Your system also generates unique names for blocks and sectors, and unique numbers of streets and houses. You must design the class structure yourself. 25 marks in this lab are for good class structure and good decisions regarding inheritance/composition.A society has many blocks, each block has many sectors, each sector has many streets, and each street has many houses. The society has a name, each block has a name (an alphabet), each sector has a name (an alphabet), each street has a number, and each house also has a unique house number.When your program starts:• It asks the user the name of the Society as well as the City in which it is located. Your program should be able to handle input that has more than one words.• Then, it asks the user how many blocks does this society has.…

You are given a template to help you follow the required structure. There are 10 files for the base and derived classes with specification and implementation files You are also given a driver MagicalCreaturesMain.cpp that you will complete. So 11 files in all. MagicalCreatureHeader.h // given to you MagicalCreature.cpp // given to you ElfHeader.h // given to you Elf.cpp // you implement methods DragonHeader.h // given to you Dragon.cpp // you implement methods GoblinHeader.h // given to you Goblin.cpp // you implement methods GenieHeader.h // given to you Genie.cpp // you implement methods Specifications: Here are five UML Diagrams: One for the Base class and the others for the derived classes. Use these along with the given template to complete the design of the classes and create the application. The template contains comments and notation as to where you need to fill in the code;…
You have to implement program that compares graduate students based on their ranks. The design of the program is given in the following UML diagram: • Student class: Base class that GradStudent extends. • GradStudent class: The objects from this class will be used for comparisons. • Rankable interface: Defines the implementation needed for comparison. GradStudent implements this interface. • Test class will be used to get student information from the user and demonstrate the comparison of students.
Scenario:You are hired by a game development company. Your task is to create an RPG hack & slash console game. The game will have a movement system that will be based on the x, y, z coordinate system. You will need to start with creating 3 classes.1. A class that represents a player2. A class that represents an enemy3. An abstract class that contains the movement logic.Step 1:Start by creating the superclass which defines the movement system for both enemy and player. The movement system is based on the Coordinate system. Imagine an x, y, z plane, the y coordinate is used to move forward and backward in the virtual plane, x to go left and right, z to go up and down.For example, A player with coordinates x, y, z with values -5, 10, 0 represents a player -5 units to the left, 10 units forward, and 0 z units mean on the ground. (0, 0, 0) are the base units which means the player or enemy is at the start of the level.Step 2:Create a class to represent the player which is derived from…
Consider the following scenario: A chicken, eagle and duck are birds. A dog, cat, cow,and lion are animals. Human and Birds are also animals. Peas, carrots, and grass areplants. Chicken, duck, cow, and plants are edible. Draw a class diagram for the abovescenario. You can use classes, inheritance, interfaces, and associations (includingcomposition or aggregation) when needed. You shouldn’t use operations.
In-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract. Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0 Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: # Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: # Write a TestShape class that has the main method, which creates…
We are working in 2D and programming in C#. Create a Point class to represent points in 2D. Create an abstract base class named Shape. It should have a position property as a Point. It should be designed as having Move and Resize methods. Create a Line class using Points, derived from Shape class. Its position should be the center of the line. Create a Polygon class representing a closed polygon of Lines, derived from Shape class. Note that, at construction time, Lines may not be provided in order. The continuity and number of the lines should also be checked for a properly closed Polygon. All geometric entities should be moveable. All shapes should be resizable without changing their central positions. All shapes' positions should be their centroids. Shapes should have areas calculated. Write an example C# Console code to demonstrate your program's abilities.

In this exercise, you have to perform composition between the Toyota class and its Engine! Problem Statement# You have to create a Toyota class which inherits from a Car class, and is composed of an Engine Note: You already know that in such a composition relation, the oyota class will be res ible for Engine's lifetime. Consider this diagram for reference Car - id: int model: String - color: String + carFeatures(): void +setModel(): void + setColor(): void Toyota ToyotaEngine **** start): void stop): void . ..... + setStart(): void Part of- Car, Toyota and ToyotaEngine: Class Representation You should implement the Toyota class as the child class of the Car. It should have an instance of ToyotaEngine and a setStart() function which in turn calls the start () function of the ToyotaEngine class. The start () and stop () functions of ToyotaEngine class simply print out on screen that the engine has been started/stopped.
