- 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 languageCreate a Java class that describes a product in a store with relevant fields. A few examples of such fields would be name, brand, etc. Append the class with methods that allow a customer to buy that product and append the number of times the product is sold. The customer will be subjected to 13% tax on each buy, you will calculate the payable amount and display it on the console on each buy.In Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!
- Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details.

- Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2+5= Your class needs to contain two constructors, one that takes String, int, int that represents the operator sign(+,-, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…Please help with the following: C# .NET change the main class so that the user is the one that as to put the name Write a driver class (app) that prompts for the person’s data input, instantiates an object of class HeartRates and displays the patient’s information from that object by calling the DisplayPatientRecord, method.

- Java Assignment Outcomes: Student will demonstrate the ability to utilize inheritance in a Java program. Student will demonstrate the ability to apply the IS A and HAS A relationships. Program Specifications: Start by watching Video Segment 16 from Dr. Colin Archibald's video series (found in the module overview). Key in the program shown in the video and make sure it works. Then, add the following: Animals have a Weight. Animals have a Height. Dog is an Animal. Dogs have a Name. Dogs have a Breed. Dogs have a DOB. Cat is an Animal Cats have a Name. Cats have 9 lives, so you need to keep track of the remaining lives once a cat dies. Bird is an Animal Birds have a wing span Birds have a canFly which is true or false (some birds cannot fly) Create a test class that creates one of each type of animal and displays the animal’s toString method. Submission Requirements: You must follow the rules from the prior assignments. UMLs and Design Tools are not required for this one. YOU MAY…Note : ALL Code Must be in OOP (JAVA) And perform all in ecplis (console base) Scenario:You are hired by a game development company. Your task is to create an RPG hack & slashconsole game. The game will have a movement system that will be based on the x, y, zcoordinate system. You will need to start with creating 3 classes.1. A class that represents a player2. A class that represents an enemy3. An abstract class that contains the movement logic.Step 1:Start by creating the superclass which defines the movement system for both enemy andplayer. The movement system is based on the Coordinate system. Imagine an x, y, z plane,the y coordinate is used to move forward and backward in the virtual plane, x to go left andright, z to go up and down.For example, A player with coordinates x, y, z with values -5, 10, 0 represents a player -5units to the left, 10 units forward, and 0 z units mean on the ground. (0, 0, 0) are the baseunits which means the player or enemy is at the start of the…Using c ++ write a class named Reservation with the following features and functionality. • Flight number Passenger name • Reservation number Number of passenger baggage • Type the method that prints the reservation information on the screen.
