- 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 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.The class "Student" has the following attributes: studentId (int), name (String), surname (String), deptCode (String).Write a constructor method for the "Student" class that takes values as parameters for all these attributes.
- Implement the Figure hierarchy shown in Figure 9.3. Each Two-DimensionalFigure must contain the getArea method to calculate the area of the two-dimensional figure.Each Three-DimensionalFigure must have getArea and getVolume methods to compute the surface area and volume, respectively, of the three-dimensional figure. Create a program that uses an array of Figure references to objects of each concrete class in the hierarchy. The program should print a text description of the object to which each element of the array refers. Also, in the loop that processes all the shapes in the array, determine whether each shape is a Two-DimensionalShape or a Three-DimensionalShape. If it is FigureTwo-Dimensional, show its area. If it is a Three-Dimensional Shape, show its area and volume.Challenge exercise The following object creation will result in the constructor of the Date class being called. Can you write the constructor’s header? new Date("March", 23, 1861) Try to give meaningful names to the parametersClasses – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.
- Implement the critter class. Each critter C has attributes species, size, and age. • The constructor accepts arguments for the attributes above, in the order above. You can expect size and age to be numeric values. Each critter C has a can_eat () method, which: Receives one argument, prey, which you can expect to be another Critter object. Compares prey 's size against C's. o If C is larger than prey, return True. Otherwise, return False. Each critter C also has a survive_year () method, which: • Increases C's size and age by 1, respectively, and returns C's current size.Create another class Teacher that will inherit properties and functionalities from personclass. Teacher class will have experience data member and an array of subjects taught bythat particular teacher.. Provide setter and getter methods for all data members.. The teacher is allowed to teach at least 2 subjects.. Perform input validation in setSubject() function so the user will not be able to inputanything except string value.. Default experience of the teacher will be 2 years.. The parameterized constructor of person class will be called using the teacher classconstructor. This will initialize all the data members of person class.. Using teacher class object display every info of teacher.Ro-Sham-Bo. Believe it or not, the classic game of Rock-PaperScissors has many other names. One of them is Ro-Sham-Bo. For this assignment, “Ro” will represent “Rock”, “Sham” will represent Paper, and “Bo” will represent Scissors. You will create a RoshamboPlayer class. It will have three attributes: PlayerName: String RoLimit: int ShamBoLimit: int It will also have an overloaded constructor that sets those three values. It will have two functions: playRound that takes in a string and returns a boolean value, and getName that takes in nothing and returns the PlayerName string. In your driver class for this assignment, you will create two RoshamboPlayer objects with the following values: p1: RoLimit == 30, ShamBoLimit == 60 p2: RoLimit = 40, ShamBoLimit = 85 You may name them whatever you like. You will prompt the user to choose one of these two to play against. Then you will create a loop that prompt the user to either play a round of Roshambo, or quit the game. If the user chooses…
- This is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player's score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class import pygame import abc import random class Drawable(metaclass - abc. ABCMeta): def --init(self, x- 0, y -0): self.x - x self.y - y self.position - (self.x, self.y) self.visible - False def setloc(self, p): self.x - p[0] self.y - p[1] def getloc(self): return(self.x, self.y) def getX(self): return self.x def getY(self): return self.y eabc.abstractmethod def draw(self, surface): pass eabc.abstractmethod def get_rect(self): passB elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…Use the parent classes to the left to help you solve this problem. The first parent is the Person class with some very generic information. The second class, CardHolder, is the class for a credit card holder. Create the child class PlantinumClient. This class inherits all of the attributes of both parent classes. In addition, the child class has the attributes cash_back and rewards. cash_back should be set to 0.02 and rewards should be set to 0. Override the process_sale method so that 2% of each sale is added to rewards. Expected Output Declare an instance of the PlatinumClient class as shown below. platinum = PlatinumClient("Sarah", "101 Main Street", 123364) Your class should be able to execute the code below in the stated order and produce the given return values. Order Code Return Value 1 platinum.process_sale(100) N/A 2 print(platinum.rewards) 2 3 print(platinum.balance) 100 4 platinum.make_payment(50) N/A 5 print(platinum.balance)…
