- B - RobotFriend Create a RobotFriend class. RobotFriend is a new toy just on the market. Copy the starter class and the tester from Codecheck. A RobotFriend has a name and replies to various commands Provide a constructor that takes the name of the RobotFriend as a parameter. Remember that a constructor has the same name as the class. What does the class need to remember? That is the instance variable. Provide the following methods: public String getName () gets the name of this RobotFriend • public void setName (String newName) sets a new name for this RobotFriend • public String whatDoYouNeed () returns a string consisting of name + needs a battery charge" where name is the name of this RobotFriend (which was supplied in the constructor) public String doCommand (String whatToDo) returns a string consisting of "Your friend " + name + does not + whatToDo where name is the name of this RobotFriend and whatToDo is the parameterJava- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Write the Movie class. The UML diagram of the class is represented below: 1. Implement the class strictly according to its UML one-to-one (do not include anythingextra, and do not miss any data fields or methods). 2. Implement a MovieTest class to test the class Movie you just created.• Create two Movie objects: one using the no-args constructor and one from theconstructor with all fields.• Print the contents of both objects. Please submit a screenshot. Hint: toString()method.
- Create a project to play a bunch of games. Add a class that has main() in it. Create an abstract class called Game. Define one instance variable for the name of the game. Define a constructor that takes the name of the game as a parameter and sets it. Define an abstract method called playGame. It takes no arguments and returns void. Create a child class of Game called BoardGame. Rather than implementing playGame, declare BoardGame abstract. Create a child class of BoardGame called Chess or Battleship or Monopoly or whatever board game you want. Implement the playGame with only a message that says the name of the game and that it is being played. Create a child class of Game called CardGame. Rather than implementing playGame, declare CardGame abstract. Create a child class of CardGame for War. Implement the playGame method by with a message that says the game of war is being played. Create a child class of Game called VideoGame. Rather than implementing playGame,…Make a class Person, with instance variable name, age, and gender. Make a class Employee inheritfrom Person, with extra data for salary, and hiring date. Make another class Student inherit from Person,with data for program name, level (undergraduate/graduate), and program year. Supply required methods forthe superclass and the subclasses. Make a subclass Manager from Employee, with bonus salary, andoverride the corresponding method(s). Provide toString method for the Employee class and its subclass,Manager, such that it returns employee name, type of the employment, and salary. For instance if you createan object, manager1, from Manager class, with name=”John Smith” and annual salary of $125,000 and bonusweekly bonus of $200, and then write a print statement like System.out.println(manager1); , the output willbe:John Smith, Manager, Salary = $125,000/year, Weekly bonus = $200Implement the following using JAVA: a.Design a class named Person and its two subclasses named Student andEmployee. b.Make Faculty and Staff subclasses of Employee. Please note that,● A person has a name, address, phone number, and email address. A student has aclass status (freshman,sophomore, junior, or senior). You can define the status as aconstant.● An employee has office & salary.● A faculty member has office hours and a rank.● A staff member has a title. c. Draw a UML diagram of the system.
- Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…Write a class named Person with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the Customer class in a simple program. All your programs will be modular. It will have the main() method that is executed first. Submit code that has no syntax error. And test your code, so as to not have logic errors. Each program must contain your name in the comments section and the date you created the code.NOTE: READ CAREFULLY Design a class named Person and a subclasses named Employee. Make Teacher a subclass of Employee. A Person has a name, address, and e-mail address. An Employee has an office, salary. A Teacher has office hours and a subject they teach. They also have a tenure status. Define the tenure status as a constant. The tenure status is either Senior or Junior, and is represented as an integer, where Senior is equal to 1, and Junior is equal to 2. Each class should have a Default constructor, and a constructor that accepts all arguments. There should be appropriate calls to the superclass within the constructors. Each class should also have getters and setters for each member variable. Each class should have a toString method. Note: You do NOT need to run this in a test program. Just create the classes as indicated above.
- Design a console program that will print details of DVDs available to buy. Make use of an abstract class DVD with variables that will store the title, yearReleased, running time and price of a DVD. Create a constructor that accepts the title, yearReleased and running time through parameters and assign these to the class variables. Create an abstract set method for the price of a DVD; also create get methods for the variables.Create a subclass InstructionalDVD that extends the DVD class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String ShowDetails();}The InstructionalDVD subclass has a private variable named category for which a get method must be written. The constructor of the InstructionalDVD class must accept the title, yearReleased, running time and category through parameters. Write the code for the setPrice() and ShowDetails() methods.Write a useDVD class and instantiate 2 objects of the InstructionalDVD…Create a class BeautyProduct with name, color, brand. Provide Constructors, getters, setters and also write toString method. Now create a class Lipstick which extends the class BeautyProduct as Lipstick is-a Beauty Product it has totalVolume, remainingVolume, price, texture (gloss, matt) as private data members. Provide Constructors, getters, setters and an apply() method whenever this method is called a beauty item is applied and its volume decreases by 10.This should also check that volume must not be zero if it then u have to throw exception. Also write toString method which prints all details like name, color, brand, price, texture and volume. Create another class foundation having totalVolume, remainingVolume, price, texture (liquid, cake) and lastingTime (number of hours foundation remain intact on face and does not crease) as private data members. This also extends the base class i.e. BeautyProduct. Provide Constructors, getters, setters and an apply() method whenever this…This assignment requires one project with two classes.
