- Help, I making a elevator simulator. I have to use polymorphism and object oriented programming to write this code. Can someone please help me improve this code I have. The remaining code is in the pictures. Any help is appreciated. Thank You! The simulation should have 4 types of Passengers: 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. The simulation should also have 4 types…The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…In this question, we will bake a class. Create a class Cake , with the following instance attributes: • name (a string) • ingreds (a list of strings) • price (a float) The Cake class has also the following methods: • Write a constructor that takes as input a string indicating the cake name, and a list of strings indicating the cake ingredients. (No docstring needed.) The constructor uses these values to initialize the attributes accordingly. Note that each cake should be assigned a random price between $10.00 (inclusive) and $15.00 (exclusive). You may import random . Moreover, a cake must contain at least three or more ingredients. If this is not the case, the constructor should raise a ValueError . For this constructor, do not worry about making a copy of the input array. You can simply copy the reference received as input into the corresponding attribute. 1 • Write a method (including docstring) called __str__ which returns a string containing the name of the cake and its price…
- A Door Class A computer game usually has many different objects that can be seen and manipulated. One typical object is a door. Whether a player runs through a castle, attacks the forces of an evil empire, or places furniture in a room, a door often comes into play. Implement a Door class as described below as well as a TestDoor class that instantiates three Door objects labeled “Enter,” “Exit,” and “Treasure.” The “Enter” door should be left unlocked and opened. The “Exit” door should be left closed and locked. The “Treasure” door should be left open but locked. A Door class A Door object can • display an inscription, • be either open or closed, and • be either locked or unlocked. Here are some rules about how Door’s work. • Once the writing on a Door is set, it cannot be changed. • You may open a Door if and only if it is unlocked and closed. • You may close a Door if and only if it is open. • You may lock a Door if and only if it is unlocked, and unlock a Door if…1. Define a class named Randomwalker. A Randomwalker object should keep track of its (x, y) location. All walkers start at the coordinates (0, 0). When a walker is asked to move, it randomly moves either left, right, up or down. Each of these four moves should occur with equal probability. The resulting behavior is known as a "random walk." (A 2-dimensional random walk example is pictured at right.) Each Randomwal ker object should have the following public methods. You may add whatever fields or methods you feel are necessary to implement these methods: move () Instructs this random walker to randomly make one of the 4 possible moves (up, down, left, or right). getX () Returns this random walker's current x-coordinate. getY () Returns this random walker's current y-coordinate. getsters () Returns the number of steps this random walker has taken.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.

- 2 part question I am using eclipse! Create a class Circle, which - has a field radius (double) It should have appropriate accessor and mutator. If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value. The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects. This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level. Note: Area = Pi * radius * radius Perimeter = 2 * Pi * Radius part 2 Create a subclass of Circle class ColoredCircle by implementing the ColoredShape interface. It should have a field color of type enum ShapeColor. ColoredShape.java ShapeColor.java ColoredCircle should have two constructors. One will takes one parameters radius and set the color to…Hi, I am making a elevator simulation and I need help in making the passenger classes using polymorphism. 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%.

Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. This is what I have so far // Passenger abstract classpublic abstract class Passenger { protected String type; protected int requestPercentage; public…Goal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class Now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (sample output below for an example of formatting) . New Member functions to the Recipe Class: 1. Add four member functions…
- Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 milesplease code in python Answer the following questions about this Dog class: [refer image for dog class] 1. Construct an instance of the Dog class whose name is Snickers and was born in2011 and assign that instance to a variable called myDog.2. Call the bark method so that myDog barks 3 times.3. Add a method to the Dog class called isPuppy that returns True if the dog is lessthan 1 year old.4. Add the __str__ method to the Dog class. It should return a string that includesthe dog’s name and age.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…
