Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators.

can someone help me? The questions are: 1. Add an addExerciseAdd method that adds an exercise to a private variable exercises in Exercise You don't need to create a getter or setter for this private variable. 2. Modify the constructors in Exercise so that you can create two types of workouts (let one constructor use the other; each variable can only have a value in one constructor): a training schedule with exercises, but without a trainer. a training schedule with exercises and with a trainer. import java.util.ArrayList;class Exerciseplan {private String customer;private String trainer;Exerciseplan(String customer) {this.customer = customer;}Exerciseplan(String customer, String trainer) {this.customer = customer;this.trainer = trainer;}private void printExercise(String name, String muscleGroup, Integer numberOfSets, Integer repetition, Integer restTime) {System.out.println("Oefening voor " + muscleGroup + ":" +" herhaal " + numberOfSets + " keer " +"(rust tussendoor " + restTime +…

Little debugging help The program runs correctly but doesn't follow instructions completely. Currently, I have a parameterized constructor in the circle class when it asked for default I need help to fix the circle subclass. Please Write a default constructor that initializes the name of the Circle object to "Circle". You will need to call the constructor of the parent Shape class. The program runs everything in ShapeDriver /** * Write a Circle class that extends the Shape class. Do the following:* 1. Write the class header.* 2. Write a default constructor that initializes the name of the Circle object to "Circle".* You will need to call the constructor of the parent Shape class.* 3. Write a void method printMessage() that prints the message " I have no sides".**///Your code goes herepublic class Circle extends Shape {public Circle(String myName) {super(myName);}public void printMessage() {System.out.println("I have no sides");}} /*** * Write a Rectangle class that extends the…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.
30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank you
Please help me with the question using Java. Please use compliment to explain each line of code.
If you fly in economy class, then you can be promoted to businessclass, especially if you have a gold airline card for privateflights. If you do not have a gold card, you can "reset" fromflight if the plane is full or you are late for check-in. All thesethe conditions are shown in the diagram below. Note that all statements(operators) are numbered. You run 3 tests:Test 1 - Gold card holder upgraded to business classTest 2 - Passenger without gold card remains in economy classTest 3 - Passenger who was "thrown" off the flightWhat is the statement coverage of these three tests?A. 60%B. 70%C. 80%D. 90%
