Need help for a java assignment

Question

i am having trouble with my java assignment, so i thought i will give it a try here and hope that i will get some help. ^^
the method is to load a file and try to create an object out of it. but even though the sequence of loading is correct, the method still doesn't work. there is no error in compilation and the coding seems correct to me. help?
the codes are below and if any other code is needed. ask me for it. =)
public void saveToFile(String fileName)
try
File f = new File(fileName);
PrintWriter p = new PrintWriter(f);
p.println(fileName);
p.println("***");
for(int i =0; i<categories.length; i++)
if(categories[i] != null)
p.print(categories.getCatNum());
Car[] x = categories[i].getListOfCars();
for(int q=0; q<x.length;q++)
if(x[q] != null)
if(x[q] instanceof EconomyCar)
p.print("Economy Car");
x[q].getCarNum();
x[q].getBrand();
x[q].getPrice();
else if(x[q] instanceof LuxuryCar)
p.print("Luxury Car");
x[q].getCarNum();
x[q].getBrand();
x[q].getPrice();
else if(x[q] instanceof SportCar)
p.print("Sport Car");
x[q].getCarNum();
x[q].getBrand();
x[q].getPrice();
p.println(x[q].getCarNum());
p.println(x[q].getBrand());
p.println(x[q].getPrice());
p.close();
catch(IOException e)
System.out.println("IO Error");
public void loadFromFile(String fileName)
try
File file = new File(fileName);
Scanner sc = new Scanner(file);
String shopName = sc.nextLine();
CarMart Cm = new CarMart(shopName);
while(sc.hasNextLine());
String line = sc.nextLine();
while(line.equals("***"));
int CateNum = sc.nextInt(); sc.nextLine();
Category Cate = new Category(CateNum);
String typeOfCar = sc.nextLine();
if(typeOfCar.equals("Economy Car"))
String CarNum = sc.nextLine();
String brand = sc.nextLine();
double price = sc.nextDouble(); sc.nextLine();
EconomyCar e = new EconomyCar(CarNum, brand, price);
else if(typeOfCar.equals("Luxury Car"))
String CarNum = sc.nextLine();
String brand = sc.nextLine();
double price = sc.nextDouble(); sc.nextLine();
LuxuryCar l = new LuxuryCar(CarNum, brand, price);
else if(typeOfCar.equals("Sport Car"))
String CarNum = sc.nextLine();
String brand = sc.nextLine();
double price = sc.nextDouble(); sc.nextLine();
SportCar s = new SportCar(CarNum, brand, price);
sc.close();
catch(FileNotFoundException a)
System.out.println("Filename not found");
