What does this do exactly?

Question

Hi,
I have this piece of code:
      // create a buffered text file stream
      BufferedReader inFile = new BufferedReader(new FileReader(args[0]));
      // data and maintenance variables
      AirlineTicket[] data = new AirlineTicket[10];
      String dataString;
      String inSeat, inName;
      double inPrice;
      // cycle through each element of the array
      for (int i = 0; i < data.length; i++)
         // read a line from the file
         dataString = inFile.readLine();
         // read and tokenise string
         StringTokenizer tokens = new StringTokenizer(dataString, ":");
         // create instance from data tokens
         inSeat = tokens.nextToken();
         inName = tokens.nextToken();
         inPrice = Double.valueOf(tokens.nextToken()).doubleValue();
         String inOrigin = "";
         if (tokens.hasMoreTokens())inOrigin = tokens.nextToken();
         // put the data into data[i]
         data[i] = new AirlineTicket(inSeat, inName, inPrice);
      }and I'm wondering how this works. Does it put inSeat, inName, and inPrice in data? How on earth does it do that? How would you access the individual seat numbers, prices, and names through that?

Hi,
All it does is go through data at j, using this method to print out the seat, name, and price:
   // displayTicket(): display an airline ticket
   private static void displayTicket(AirlineTicket in)
      // create a currency formatter for Australian English
      NumberFormat cash = NumberFormat.getCurrencyInstance(new Locale("en", "AU"));
      // display seat and name
      System.out.print(in.getSeat() + "\t" + in.getName() + "\t");
      // display costs
      System.out.println(cash.format(in.getExTaxCost()) + "\t" + cash.format(in.getIncTaxCost()));
   }It uses this code to go through each iteration of j:
               // run through array and print all data
               for (int i = 0; i < counter; i++)
                  AirlineTicket aTicket = data;
displayTicket(aTicket);
System.out.println();
I'm sorry I messed the code tag in that last post,
