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

T/F1. However, implementation classes may be extended, but interface classes cannot.
The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown. Complete the following file: sloth_Tester.cpp #include <iostream>using namespace std; #include "critter.h" /**A sloth eats and sleeps.*/class Sloth : public Critter{public:Sloth();. . .private:. . .}; Sloth::Sloth(){. . .} void Sloth::act(){if (...) {add_history("eat");...}else{add_history("sleep");... }} int main(){Sloth sloth;sloth.act();cout << sloth.get_history() << endl;cout <<…
Create an abstract CardGame which contains a “deck” of 52 playing cards that uses a Card class that holds a suit and value for each Card object. It also contains an integer field that holds the number of cards dealt to a player in a particular game. The class contains a constructor that initializes the deck of cards with appropriate values (e.g., “King of Hearts”), and a shuffle() method that randomly arranges the positions of the Cards in the array. The class also contains two abstract meb. Create two child classes that extend CardGame. You can choose any games you prefer. For example, you might create a Poker class or a Bridge class. Create a constructor for each child class that initializes the field that holds the number of cards dealt to the correct value. (For example, in standard poker, a player receives five cards, but in bridge, a player receives 13.) Create an appropriate displayDescription() and deal() method for each child class.
This is a polymorphism assignment I can't seem to figure out for Java Create an abstract class named Shapes. The Shapes class has only the calcArea() method. From Shapes, create three derived classes named Circle, Square and RightTriangle. Each of the three should have data members used to calculate the area of its shape. Define the method calcArea() for each of the three shapes. Each of the three shapes should also have appropriate constructors. Not required, but create a class with the main() method to test the classes created above.
Create an abstract class called Shape with the protected member String shapeName. It should have two public abstract methods getArea and getVolume. Finally, it should contain a public String method called getName which returns the shapeName. You should create a Circle class, Square class, Rectangle class, Triangle class which extend the Shape class. Each class should contain the necessary private variables. For example, a square has a side. The area and the volume can all be derived from the side value so the only private variable necessary for the square class is the side. The circle requires a radius. The triangle requires a base, length and a height. Finally, the rectangle requires length, height and width. The classes should also contain constructors and appropriate implementations of the two abstract methods getArea and the getVolume. **Shape Calculator** Enter 1 for a Circle Enter 2 for a Square Enter 3 for a Rectangle Enter 4 for a Triangle Enter 5 to Exit You should use a…
Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
Your assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…
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…

Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.
