public ArrayList<Bus> loadBuses(String bfile) {

ArrayList<Bus> buses = new ArrayList<>();

try {

Scanner scanner = new Scanner(new File(bfile));

while (scanner.hasNextLine()) {

String[] line = scanner.nextLine().split(" ");

if (line.length < 4 || line.length > 7) {

throw new IllegalArgumentException("Invalid input format");

}

String name = line[1];

int size = Integer.parseInt(line[1]);

int price = Integer.parseInt(line[2]);

int level = Integer.parseInt(line[3]);

Ministry ministry = null;

if (line.length > 5) {

ministry = new Ministry(line[5]);

}

int competitorArea, numSecurity, barArea;

Bus bus;

SportsBus sportsBus;

PartyBus partyBus;

switch (line.length) {

case 4:

buses.add(new Bus(name, size, price, level, ministry));

break;

case 5:

int teacherArea = Integer.parseInt(line[4]);

bus = new Bus(name, size, price, level, ministry);

TrainingBus trainingBus = new TrainingBus(bus, teacherArea);

buses.add(trainingBus);

break;

case 6:

competitorArea = Integer.parseInt(line[5]);

numSecurity = Integer.parseInt(line[5]);

bus = new Bus(name, size, price, level, ministry);

sportsBus = new SportsBus(bus, competitorArea, numSecurity);

buses.add(sportsBus);

break;

case 7:

competitorArea = Integer.parseInt(line[5]);

numSecurity = Integer.parseInt(line[6]);

barArea = Integer.parseInt(line[6]);

bus = new Bus(name, size, price, level, ministry);

sportsBus = new SportsBus(bus, competitorArea, numSecurity);

partyBus = new PartyBus(sportsBus, barArea);

buses.add(partyBus);

break;

}

} catch (FileNotFoundException e) {

e.printStackTrace();

}

return buses;

}

fix this so i can get output like this : 1;BUS_SML;100;200
2;BUS_BIG;850;20000 instead of this: 1;200;100;200
2;20000;850;20000

As you can see the BUS_SML AND BUS_BIG is missing please help
