GeometricObject must ensure that its children must implement calcArea() method. Design Rectangle18-ARID-2891 and CircleM.JibranAkram Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length
JAva Implement a class Robot that simulates a robot wandering on an infinite plane. The robot is locatedat a point with integer coordinates and faces north, south, east, or west. Supply methods:public void turnLeft()public void turnRight()public void move()public Point getLocation()public String getDirection()The turnLeft and turnRight methods change the direction but not the location. The move method movesthe robot by one unit in the direction it is facing. The getDirection method returns a string “N”, “S”,“E”, “W”. For the new object, the initial location and facing should be specified. For the initial facing, 0means north, 1 means east, 2 means south, and 3 means west.A tester class, RobotTester, has been provided as follows to help you how to implement the Robot class.Therefore, implement the Robot class such that the following RobotTester class can be executed withoutany changes.import java.awt.Point;/**A class to test the Robot class.*/public class RobotTester{/**Tests the…
Define a Polygon interface that has methods area() and perimeter(). Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. Also implement classes, IsoscelesTriangle, Equilateral- Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. Finally, write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then out- put their area and perimeter. For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar ORIGINAL WORKS ONLY
Task: Implement a class ChessPiece with properties: color, isAlive, moveCount, and position (x, y coordinates). Define an abstract move method. Create a Tower subclass that overrides move for specific behavior. Instructions: ChessPiece Class: Properties: String color, boolean isAlive, int moveCount, Position position. Abstract Method: move(int x, int y). Position Class: Contains int x, int y. Tower Subclass: Extends ChessPiece. Overrides move for straight line movement. Deliverable: Source code for ChessPiece, Position, and Tower. Document class functionalities briefly.

Create a python program for the following details: Create an abstract class Shape Under Shape create abstract methods name, sides, and color. Create subclasses of Shape with the name Square, Pentagon, and Triangle. Under each subclass, implement the methods name, sides, and color with the following details. Square: print "Square", "I have 4 sides", "My color is yellow" Pentagon: print "Pentagon", "I have 5 sides", "My color is blue" Triangle: print "Triangle", "I have 3 sides", "My color is red" Create an instance of each subclasses. Ask the user for an input. (Assume the user will input 3, 4, or 5 only) if the user input 3 - print the details of an object of subclass Triangle if the user input 4 - print the details of an object of subclass Square if the user input 5 - print the details of an object of subclass Pentagon SAMPLE INPUT 1. num SAMPLE OUTPUT NEEDED: Enter a number: 3 Triangle I have 3 sides My color is red

Java Problem A shop sells beverages. A beverage has a brand, the ingredients, a codebar number, price, production date and expiration date. A beverage belongs to a company that has a name, an address, a phone number and an email. The shop employees want to check automatically the stock of beverages. All expired or sold beverages need to be eliminated. Implement the Shop, Beverage and Company classes. Implement the needed interfaces and methods for the classes. The shop has a method which specifies how many times does each ingredient appear in the whole collection of beverages. Create a main method which tests the program with relevant data based on data which is read from a file and output the beverages which are out of stock in a file.
Java Computer Programming. Each robot: - Has a name (attribute name: string) - Has a position: given by the integer attributes x and y. - Has a direction: given by the direction attribute that takes one of the values "North", "East", "South" or "West". The name, position and direction of a robot are given to it at the moment of its creation - Can advance one step forward: with method without parameter advance () - Can turn right 90 ° to change direction (if its direction was "North" it becomes "East", if it was "East" it becomes "South", etc.): with the method without parameter right(). Robots cannot turn left. - Can display its detail with the method detail() Detail: name, position, and current direction.
FOR JAVA 1. Implement the following classes and interface in Java. Shape interface which has the following methods: – public double perimeter(); // doesn’t have any parameters, re- turns the perimeter of the shape. – public double area(); // doesn’t have any parameters, returns the area of the shape. – public void info(); // doesn’t have any parameters, prints the perimeter and area of the shape. Circle class that implements Shape interface and has a constructor that takes the radius. Rectangle class that implements the Shape interface and has a con- structor that takes the width and height. Square class that extends the Rectangle class and has a constructor that takes the edge length. – Square constructor should only call the super constructor with correct parameters. – Square constructor should not explicitly implement the Shape class, but it should inherit the perimeter, area and info methods from the Rectangle class. 2. Create a Test class, and create one…
