‏java programming Robot Class : a robot has a name , located at a point with integer coordinates , faces north , east , south , or west and keeps a record of all its movements positions . The class has the following methods : A default constructor that initializes robot's name to " Unknown ” , location to ( 0,0 ) , direction to North , and travelled distance to 0 , and simulated movements to null . A constructor that given robot's name , starting location , and facing direction , Accessor methods to access all the instance variables and the simulated movements of the robot Mutator methods that change the instance variables to given values and they made the change for only suitable values . tumLeft and turn Right methods that change the direction of the robot but not the location move method that moves the robot by one unit in the direction it is facing . get Travelled Distance method that retums how many units has the robot moved .
*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
# 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…
Course Title: Modern Programming Language Please Java Language Code and Correct Code Please Question : Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design Rectangle18ARID2891 and CircleMJibranAkram Classes as children of GeometricObject class with overridden toString() method to return “Rectangle18ARID2891 with w Width and h Height is drawn” OR “CircleMJibranAkram with r Radius is drawn”. The attributes of Rectangle18ARID2891 are length, width. The attribute of CircleMJibranAkram is radius Hint: Area of circle=πr2 , Area of rectangle= width*length

In java language on netbeans design a console application that will print the game sales for a particular game in 2021. Use an abstract class named Games that contains variables to store the game name, game genre and the total sales. Create a constructor that accepts the game name, game genre and the total game sales as parameters. In this class also create get methods for the variables. The Games class must implement an iGames interface that contains the following: public interface iGames { public void printSales(); public String getGame(); public String getGameGenre(); public int getGameSales(); } Create a subclass called Game Sales that extends the Games class. The Games Sales class must contain a constructor to accept the game name, game genre and total game sales as parameters. Then, write code for the Print Sales method, which prints the game sales report for 2021. Finally, write a Use Games class to instantiate the Games Sales class.

In Java: Implementing a Superclass Employee Part 1: Implement a superclass Employee that has the following fields and methods. Fields: string firstName string lastName int employeeID double salary Methods: constructor method - initialize salary field to zero. setters and getters for firstName, lastName, and employeeID employee Summary method - prints all account attributes Part 2: Implement a Manager class that inherits from the Employee class. Fields: string department a Methods: employeeSummary method - prints all superclass and subclass attributes Ensure that your program has the two required classes and a test class.
