Arraylist.add() problem

Question

Hi,
I'm trying to read a CSV text file into an arraylist.
I can read the text file fine, its just when it gets to the actual arraylist.add() part it just .. .. doesn't work. It can print the values from the CSV file no problem. I'm sure my syntax is fine, everything compiles. I've read it and double checked it and checked it again.
It just doesn't work .. I don't know why.
The arraylist I am trying to read into is
ArrayList<Customer> customers = new ArrayList<Customer>();Within other parts of the program I can read in dummy data, eg
customers.add(new Customer(01, "Jims Mowing", "16 Long Grass Street", "Thorndale", "123-4567", "[email protected]"));
but suffice to say, yes, it is kaput.
   * READING THE CUSTOMER TEXT FILE INTO THE ARRAY LIST
  private void custFileToArray ()
    RectangleTUI results = new RectangleTUI(); // create results object
    try   
      BufferedReader inputStream = new BufferedReader(new FileReader(PATHNAME + CUSTFILE));
      System.out.println("Contents of file: " + CUSTFILE); // print heading
      String line = inputStream.readLine(); // read first line
      while (line !=null) // test for end of file (EOF)
        results.loadCustFile(line);       
        line = inputStream.readLine(); // read next line
      // close file
      inputStream.close();
    // catch any file open errors
    catch(FileNotFoundException e)
      System.out.println("Error opening file: " + CUSTFILE);
      System.exit(0);
    catch(NoSuchElementException e)
      System.out.println("ATTENTION: One or more " + CUSTFILE + " records are missing data");
    // catch any file reading errors
    catch(IOException e)
      System.out.println("Error reading from file: " + CUSTFILE);
      System.exit(0);
    System.out.println("File Reading Complete");  
  private void loadCustFile(String textLine)
    String delimiters = ","; // set tokenizer delimiter
    StringTokenizer RecordFields = new StringTokenizer(textLine,delimiters);  
    int cidNum = Integer.parseInt(RecordFields.nextToken()); // Customer ID
    System.out.println(cidNum + " Hello I am a stupid piece of code. I don't like to work properly");
    String cName = RecordFields.nextToken();   // Name
    String cAdd = RecordFields.nextToken();   // Street Address
    String cBurb = RecordFields.nextToken();   // Suburb
    String cPhone = RecordFields.nextToken();   // Phone
    String cEmail = RecordFields.nextToken();   // Email
    customers.add(new Customer(cidNum, cName, cAdd, cBurb, cPhone, cEmail));
  }

Hi,
Cheers for the replies & the printStackTrace tip.
The thing is it's not actually throwing up any errors or crashing. It's acting as if everything is AOK - but since it then says there's nothig in the arraylist there must be a problem ... somewhere.
Sorry if I've mis-understood what you were saying
Here's the dummy data I'm using just incase it's at all relevant
