- Create a project to play a bunch of games. Add a class that has main() in it. Create an abstract class called Game. Define one instance variable for the name of the game. Define a constructor that takes the name of the game as a parameter and sets it. Define an abstract method called playGame. It takes no arguments and returns void. Create a child class of Game called BoardGame. Rather than implementing playGame, declare BoardGame abstract. Create a child class of BoardGame called Chess or Battleship or Monopoly or whatever board game you want. Implement the playGame with only a message that says the name of the game and that it is being played. Create a child class of Game called CardGame. Rather than implementing playGame, declare CardGame abstract. Create a child class of CardGame for War. Implement the playGame method by with a message that says the game of war is being played. Create a child class of Game called VideoGame. Rather than implementing playGame,…java You are part of a team writing classes for the different game objects in a video game. In this assessment you are given a superclass (Human.java), two subclasses (Warrior.java and Wizard.java) and a test application (TestGameObjects.java). Both the Warrior and the Wizard classes need to be able to calculate stealth. This needs to be done in the method getStealth. This method has an integer parameter (dexterity) and returns an integer. Refer to the test application to see how the method is used. The Warrior and Wizard classes calculate stealth differently: The Warrior's stealth is equal to dexterity times strength (dexterity * strength) while the Wizard's stealth is equal to three times dexterity times intelligence (3 * dexterity * intelligence). You need to write an interface with the method getStealth, and then modify the superclass and subclasses to implement this interface. You also need to test the validity of the object ID. The object ID must consist of the character 'W'…Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230
- Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. A data field radius with a get method. A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b). A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. Figure (a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another circle. Draw the UML diagram for the class.…Classes – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.Create an abstract class named Element that holds properties of elements,including their symbol, atomic number, and atomic weight. Include aconstructor that requires values for all three properties and a get method for each value. (For example, the symbol for carbon is C, its atomic number is 6, and its atomic weight is 12.01. You can find these values by reading a periodic table in a chemistry reference or by searching the Internet.) Also include an abstract method named describeElement(). Create two extended classes named MetalElement and NonMetalElement. Each contains a describeElement() method that displays the details of the element and a brief explanation of the properties of the element type. For example, metals are good conductors of electricity, while nonmetals are poor conductors
- Please do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:This is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player's score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class import pygame import abc import random class Drawable(metaclass - abc. ABCMeta): def --init(self, x- 0, y -0): self.x - x self.y - y self.position - (self.x, self.y) self.visible - False def setloc(self, p): self.x - p[0] self.y - p[1] def getloc(self): return(self.x, self.y) def getX(self): return self.x def getY(self): return self.y eabc.abstractmethod def draw(self, surface): pass eabc.abstractmethod def get_rect(self): passThe total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…

A constructor that constructs a point with specified coordinates. A method named distance that returns the distance from this point to a specified point of the MyPoint type.
