Question

I need help in improving my code. This is an elevator simulator that uses polymorphism and object-oriented programming to simulate the movement of elevators in a building with multiple types of passengers and elevators.
The system has 8 elevators, each of which can be one of 4 types of elevators, with a certain
percentage of requests for each type. Similarly, each passenger can be one of 4 types, with a
different percentage of requests for each type.

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.

 

Passenger {

Should have the variable used in sub classes

initializes Passenger Counter - keeps count of number of passengers

}

Sub-classes (Standarda, Vip, Frieght, Glass) {

Use the polymorphic methods from Passenger class

requestElevator - Uses random to generate a Start floor and End floor.

getPercent - Retrieves the percent from the setting.txt file.

}

This is what I have:

public class Simulation {

    SimulatorSettings settings = new SimulatorSettings("settings.txt");

    public void InitSimulation() throws FileNotFoundException{

        ///// Read all parameters from the file and store in the clas

        File file = new File("settings.txt");

        Scanner scanner = new Scanner(file);

        //FileReader freader = new FileReader(file); 

        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 class SimulatorSettings {

    SimulatorSettings(String fileName){

        

    }

    private int nofloors;

 

    public int getNofloors() {

        return nofloors;

    }

 

    public void setNofloors(int nofloors) {

        this.nofloors = nofloors;

    }

}

        while (this.startFloor == this.endFloor) {
            this.endFloor = rand.nextInt(settings.getNofloors());
        }
        return true;
    }
}
