Course Title: Modern Programming Language Please Java Language Code Question : Design an abstract class GeometricObject. 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

# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…
Java Object Oriented Programming Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the…
Java programming lanaguage A. Design and implement the class Circle that contains the double private data field radius and the following member methods: getRadius that returns the radius of Circle setRadius that sets the radius of Circle area that calculates and return the area of a Circle object (area = π*r²). toString that returns the radius of a Circle object as a string. Two constructors; the first one without arguments. The second constructor with one parameter r. It initializes the radius to r.

Create a RightTriangle class given the following design: RightTriangle variables: base, height methods: 2 constructors, 1 that set default values and another that accepts to parameters. setBase - changes the base. Requires one parameter for base. setHeight - changes the height. Requires one parameter for height. getBase - returns the triangle base. getHeight - returns the triangle height. area - returns the area of the triangle (1/2bh) given the current base and height
The Robot class models the state and behavior of virtual robots. Each robot corresponds to an object that is an instance of this class. Each robot: properties: Has a modelNumber (int) Has a direction(String): given by the direction attribute that takes one of the values "North", "East", "South" or "West" Has a makeYear (int): the year the robot was made. Methods: Can turn left 90 ° to change direction (if its direction was "North" it becomes "West", if it was "West" it becomes "South", if it was "South" it becomes "North", etc.). with the method without parameter turnLeft () Can display its detail with the method myInfo().

Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…
