Using polymorphism and object-oriented programming Design an Elevator simulation. The simulation have 4 different types of elevators and passengers.
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.
There are 4 types of elevators in the system:
StandardElevator: This is the most common type of elevator and has a request percentage of 70%.
Standard elevators have a maximum capacity of 10 passengers.
ExpressElevator: This type of elevator has a request percentage of 20%. Express elevators have a
maximum capacity of 8 passengers and are faster than standard elevators.
FreightElevator: This type of elevator has a request percentage of 5%. Freight elevators have a
maximum capacity of 5 passengers and are designed to transport heavy items.
GlassElevator: This type of elevator has a request percentage of 5%. Glass elevators have a
maximum capacity of 6 passengers and are designed to transport fragile item
The input should look like this:
# Building parameters
floors=30
# Passengers to add to floors
add_passenger 1 6 25 Standard 30
add_passenger 2 2 28 VIP 10
add_passenger 3 7 15 Freight 20
add_passenger 4 4 20 Glass 15
# Elevator types

# Percentage of passenger requests for each elevator type

# Percentage of passenger requests for each passenger type
passenger_request_percentage Standard 70

passenger_request_percentage Freight 15
passenger_request_percentage Glass 5
# Number of elevators in the system
number_of_elevators 8
# Run simulation for 60 iterations
run_simulation 60
Use these classes to make the elevator simulation:
Main class:
public class SimulatorSettings {
SimulatorSettings(String fileName){
}
private int nofloors;
public int getNofloors() {
return nofloors;
}
public void setNofloors(int nofloors) {
this.nofloors = nofloors;
}
}
Other Classes:
public class Simulations {
while(scanner.hasNextLine()){
String line = scanner.nextLine();
if(line.startsWith("floor="))
{
line= line.replace("floor=", "");
// Convert the value to the wanted type
System.out.println(line);
}
}
settings.setNofloors(55);
Passenger pass1 = new StandardPassenger();
pass1.requestElevator(settings);
ArrayList<Passenger> passengers = null;
for(int i = 0; i < 100; i++){
//Use the percentage from the file
passengers.add(new StandardPassenger());
}
}
}
public abstract class Passenger {
public static int passangerCounter = 0;
private String passengerID;
protected int startFloor;
protected int endFloor;
Passenger(){
this.passengerID = ""+passangerCounter;
passangerCounter++;
}
public abstract boolean requestElevator(SimulatorSettings settings);
}
public class StandardPassenger extends Passenger{
private String type;
public StandardPassenger() {
}
public boolean requestElevator(SimulatorSettings settings){
Random rand = new Random();
this.startFloor = rand.nextInt()% settings.getNofloors();
this.endFloor = rand.nextInt() % settings.getNofloors();
while(this.startFloor == this.endFloor){
this.endFloor = rand.nextInt() % settings.getNofloors();
}
return true;
}
}
And make Other 3 passengers classes that use polymorphism.
public class Elevator {
private int currentFloor = 0;
private int maxFloor;
public int getCurrentFloor() {
return currentFloor;
}
public int getMaxFloor() {
return maxFloor;
}
public void setCurrentFloor(int currentFloor) {
this.currentFloor = currentFloor;
}
public void setMaxFloor(int maxFloor) {
this.maxFloor = maxFloor;
}
}
And make Other 4 elevator classes that use polymorphism.

- The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun…arrow_forwardThe Point2D should store an x and y coordinate pair, and will be used to build a new class via class composition.

- For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality.

- Brainstorm below how you want to organize a game state class. This class keeps track of all information required to run the game. Remember, a class is composed of: State (data that is stored about an object) Behavior (behaviors of an object) For example, if you were to represent a Wordle game as a class, what data is stored within the game you’d want to have as member variables? What actions/behaviors can be taken?arrow_forwardCreate a class Person to represent a person according to the following requirements: A person has two attributes: id Add a constructer to initialize all the attributes to specific values.

Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java.
