Ask the user for a filename. Display the oldest car for every manufacturer from that file. If two cars have the same year, compare based on the VIN.

i am having trouble getting my code to work

 this is my code:

import java.util.*;
import java.io.*;
class Car {
String manufacturer;
String model;
int year;
String vin;
public Car(String manufacturer, String model, int year, String vin) {
super();
this.manufacturer = manufacturer;
this.model = model;
this.year = year;
this.vin = vin;
}
public String getManufacturer() {
return manufacturer;
}
public void setManufacturer(String manufacturer) {
this.manufacturer = manufacturer;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
public String getVin() {
return vin;
}
public void setVin(String vin) {
this.vin = vin;
}
}
class CarComparator implements Comparator < Car > {
@Override
public int compare(Car car1, Car car2) {
int yearCompare = Integer.compare(car1.getYear(), car2.getYear());
if (yearCompare != 0) {
return yearCompare;
}
return car1.getVin().compareTo(car2.getVin());
}
}
public class Demo {
public static void main(String[] args) throws FileNotFoundException {
ArrayList < Car > cars = new ArrayList < Car > ();
Scanner sc1 = new Scanner(System.in);
System.out.println("Enter filename");
String carFile = sc1.next();
File file = new File(carFile);
Scanner sc2 = new Scanner(file);
String[] carDetails;
sc2.nextLine();
while (sc2.hasNext()) {
String carLine = sc2.nextLine();
carDetails = carLine.split("\\s+");
if (carDetails.length < 2) {
continue;
}
String manufacturer = carDetails[0];
String model = carDetails[1];
int year = Integer.parseInt(carDetails[2]);
String vin = carDetails[3];
boolean flag = true;
for (Car c : cars) {
if (c.manufacturer.equals(manufacturer)) {
flag = false;
if (c.year > year) {
c.setModel(model);
c.setYear(year);
c.setVin(vin);
} else if (c.year == year) {
if ((c.vin).compareTo(vin) > 0) {
c.setModel(model);
c.setYear(year);
c.setVin(vin);
}
}
}
}
if (flag) {
cars.add(new Car(manufacturer, model, year, vin));
}
}
Collections.sort(cars, new CarComparator());
int spaces = 25;
for (Car c: cars) {
for (int i = 0; i < 20 - (c.manufacturer.length()); i++)
System.out.print(" ");
System.out.print(c.manufacturer);
for (int i = 0; i < 20 - (c.model.length()); i++)
System.out.print(" ");
System.out.println(c.model + " " + c.year + " " + c.vin);
}
System.out.println(cars.size() + " result(s)");
}
}

it is supposed to display

56 result(s)\n

but it is displaying the same error everytime

i need my code to be fixed so that is displays the information properly to display the oldest car for every manufacturer from that file and If two cars have the same year, compare based on the VIN.

i am not sure where i am going wrong with my code, the code is based on sorting and searching and algorithm analysis if an expert can implement this
