HELP!!! - Information into an Array using scanner

This message was edited 1 time. Last update was at 04/05/2007 18:11:15

Can somebody please help me with this problem. I have to initiate an array and then enter information into it via the scanner utility from a csv file. I can get the correct code to create or iterate over the array.

My code is as follows:

/**
    * This method creates a new League object by reading the required details from
    * a CSV file. The file must be organised as follows:
    *     name(String), number of teams (int)
    *     team name(String), won(int), drawn(int), lost(int), for(int), against(int)
    *        and so on for each team
    * Having created the new League object the method should create all the Team 
    * objects (using the data in the file to set their attributes) and add them 
    * to the teams array.
    */
   public static League loadLeague()
   {
      League theLeague = null;
      String pathname = OUFileChooser.getFilename();
      File aFile = new File(pathname);
      BufferedReader bufferedFileReader = null;
      Team[] teams;
      try
      {
         String name;
         int numberOfTeams;
         String teamName;
         int won;
         int drawn;
         int lost;
         int goalsFor;
         int against;
         Scanner lineScanner;
         bufferedFileReader = new BufferedReader(new FileReader(aFile));
         String currentLine = bufferedFileReader.readLine();
         while(currentLine != null)
         {
            lineScanner = new Scanner(currentLine);
            lineScanner.useDelimiter(",");
            name = lineScanner.next();
            numberOfTeams = lineScanner.nextInt();
            theLeague = new League(name, numberOfTeams);
            teamName = lineScanner.next();
            won = lineScanner.nextInt();
            drawn = lineScanner.nextInt();
            lost = lineScanner.nextInt();
            goalsFor = lineScanner.nextInt();
            against = lineScanner.nextInt();
            teams = new Team[numberOfTeams];
            for ( int i = 0; i < teams.length; i++ )
            {
               System.out.println( "Enter Score: "
               + ( i + 1 ));
               teams[i] = lineScanner.nextInt();
            }

currentLine = bufferedFileReader.readLine();
         }
      }
      catch(Exception anException)
      {
         System.out.println("Error: " + anException);
      }
      finally
      {
         try
         {
            bufferedFileReader.close();
         }
         catch(Exception anException)
         {
            System.out.println("Error: " + anException);
         }
      }
            
      return theLeague;
   }

Thanks very much in advance to anybody who can put me out of my misery.

I'll be glad to help but where are you having problems? If you're getting an error or if the program isn't running the way you want let us know some details. The more information you can provide the better.

Scottish League Division 1,10
Airdrie United ,3,2,11,14,25
Clyde ,5,7,4,21,17
Dundee ,7,2,7,21,18
Gretna ,10,3,3,43,20
Hamilton Acas ,7,5,4,19,20
Livingstone ,6,6,4,21,15
Partick Thistle,8,4,4,25,29
Queen of South ,3,3,10,11,31
Ross County ,4,4,8,14,24
St Johnstone ,6,6,4,26,16

Above is the text file that I have to get into my system. The first line goes into the 'theLeague = new League(name, numberOfTeams);' under name and this works correctly. the second numberOfTeams(10) also has to create an array of ten teams. These ten teams Airdrie United down along with the numbers have to go into an Array. I am struggling to get the array to initialise and therefore am also struggling to get any of the information into it.

Thanks in advance

The teams array is declared to hold instances of the Team class, however you're setting it to an integer.

You're going to have to invoke one of the Team class's constructors to initialize each item in the array.
