- 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 .java. Check ‘n Shop is a grocery supermarket in South Africa that provides a loyalty program to customers on a monthly basis. Customers earn points based on the number of visits and the amount they spend, especially on healthy foods during the month. The private data fields for the Shopper object class are: See attached image The constructor must assign values of the parameters to the private data field variables. The static variable should be incremented by one in the constructor. The increaseLoyaltyPoints() method calculates the number of loyalty points based on the amount a customer spent at the supermarket. All customers receive 100 free points each month. Use the following criteria to calculate the additional points earned to be added to the 100 free points: For every four rands (R4) spent, one loyalty point is awarded. Make use of an appropriate Math class function to round up the loyalty points to a whole number. The updateHealthLevel() method receive the total amount…Constructors in Java Create a constructor for the Phone class that accepts three values: brand storage price Then, ask the user for the values of these attributes.

- Java Programming: ConWay World Conway’s game of life is a simple simulation of life forms in a two dimensional grid. The ConwayCell implements the standard behavior of a call in Conway’s Game of Life. You only need to implement and test two new classes. You will create two different cells, derived from AbstractCell. 1. Alternating Cell The first class that you should create is a class named AlternatingCell. This is a cell that should alternate between being alive and dead with each generation. Add one or more of your AlternatingCells to your ConwayWorld. You can see how to add a cell in line 15 - 20 of Main.java. Give your AlternatingCell a unique display character when it is alive so that you can see it in your conway world. 2. Your own cell For the second cell you should feel free to implement any behavior that you want. If you are having trouble thinking of ideas then post up a question. You can add your custom cell in just a few places in the world, or you might choose to replace…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) Question 5 Explain the answer step-by-step and include verbal explanation.

- Java program: 1. Create a class named Rectangle that has instance variables height and width. Provide a constructor that initializes the instance variables based on parameter values, getter and setter methods for the instance variables, a toString method, and a method named computeSurfaceArea(), that returns the surface area of the rectangle. 2. Create a child class named RectPrism that contains an additional instance variable named depth. Provide a constructor, getter and setter methods for the new instance variable, and a method named computeVolume(), that returns the volume of the rectangular prism. Override the toString() and the computeSurfaceArea() methods. 3. Write an application called Demo, that instantiates a rectangle and a rectangular prism, and tests all the methods. Make sure you indent and comment your code based on the examples in the textbook. Don’t forget to include your name, the course number, title of the assignment, and today’s date.In Java: Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int).

- # 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…in java A class Book is designed to model a book written by one author.
