Question

public Bus( String name, int size, int price, int lev, Ministry mny) {

approvedTrips=new ArrayList<Trip>();

this.name = name;

this.size =size;

this.price = price;

this.level = lev;

this.id = getNextId();

this.mny = mny;

tripTypes = "BASICTRANSPORT";

}

import java.util.Scanner;

public class TrainingBus extends Bus {

private int teacherArea;

public TrainingBus(Bus b, int teacherArea)

{

super(b.getName(), b.getSize(), b.getPrice(), b.getLevel(), b.getMinistry());

this.teacherArea = teacherArea;

}

import java.util.Scanner;

public class SportsBus extends Bus {

private int competitorArea;

private int numSecurity;

private Bus bus;

public SportsBus(Bus b, int competitorArea, int numSecurity)

{

super(b.getName(), b.getSize(), b.getPrice(), b.getLevel(), b.getMinistry());

bus = b;

this.competitorArea = competitorArea;

this.numSecurity=numSecurity;

}

import java.util.Scanner;

public class PartyBus extends SportsBus{

int barArea;

public PartyBus(SportsBus s, int barArea)

{

super( s.getBus(), s.getCompetitorArea(), s.getNumSecurity());

this.barArea = barArea;

}

Here is how it's done for the bus class

case 4: //regular bus

{

Bus b = new Bus(nextLine[0], Integer.parseInt(nextLine[1]),Integer.parseInt(nextLine[2]),Integer.parseInt(nextLine[3]), mny);

blist.add(b);

break;

}

make sure the index are right for the arrays and take into consideration the constructors and what type each is for the different bus classes look at image uploaded please
