Read from file to array - problem

[adize]

Hello everyone. I have a coursework at university and my assignment is to make a set of classes for application for euro 2012. I managed to write five classes (abstract Person, Player, Manager, Country, Group) and tested it, everything works fine except one method - I was asked to write a method in Group class to read data from txt file and create Player and Manager objects from it. Person, Player and Manager are simple classes with some attributes like name, age, number of goals etc.

The Country class consists of two fields String name; Person[] squad. The Group class consists of one field private Country[] teams.

I know the basic idea how to load data from txt file, but in this particular example, I do not know exactly how to add created objects to the array (especially when it is an array in a second array (squad array in teams array). I would really appreciate your help and suggestions how best to apporach it. Thank you!

  public void readFromFile(File f){
        try {
            BufferedReader br = new BufferedReader(new FileReader(f));
            String nextLine = br.readLine();
            while(nextLine != null){
                StringTokenizer st = new StringTokenizer(nextLine,",");
                int type = Integer.parseInt(st.nextToken());
                String name1 = st.nextToken();
                String name2 = st.nextToken();
                int age = Integer.parseInt(st.nextToken());

                
                if (type == 1){
                    int squadNo = Integer.parseInt(st.nextToken());
                    int capsNo = Integer.parseInt(st.nextToken());
                    int goalsNo = Integer.parseInt(st.nextToken());
                    boolean ifCaptain = Boolean.parseBoolean(st.nextToken());
                    String position = st.nextToken();
                    Player p = new Player(name1, name2, age, squadNo, position, 
                            capsNo, goalsNo, ifCaptain);
                    //add person to array;
                } else if (type == 2){
                    int yearStart = Integer.parseInt(st.nextToken());
                    Manager m = new Manager(name1, name2, age, yearStart);
                   //add manager to array;
                } 
                nextLine = br.readLine();
            }
            br.close();
        } catch (Exception ex) {
            System.out.println(ex);
            System.exit(1);
        }
    }

Just don't use array. Use some kind of Collection. ArrayList will be good in this case.

Then just use add method.
