Weird file.nextLine() behavior

Question

Okay, so I'm having this weird issue where I'm trying to get a File to give input into several classes. Here is the method, most of which is commented out. At the specified point, I'm needed a multi-word string put in. However, while .next() works, .nextLine() fails.

New to java, so sorry if this is obvious.

public void readWeeklyData (String fileName) 
{
  try{
        File file = new File(fileName);
        Scanner fileReader = new Scanner(file);

        _leagueName = fileReader.nextLine(); //Outputs String properly despite spaces
        _leagueID = fileReader.nextInt();
        _numTeams = fileReader.nextInt();
       _numWeek = fileReader.nextInt();

      int i = 0;
      int j = 0;

       // while(i < _numTeams)
       // {
            Team team = new Team();
            team.setTeamID(fileReader.nextInt());
            System.out.println(team.getTeamID()); //Outputs 1011 properly
            team.setTeamName(fileReader.nextLine()); //Outputs nothing, with or without the while loops in comments. Yet when changed to fileReader.next(), it gives the first word of the team name.
           // team.setGamesWon(fileReader.nextInt());
          //  team.setGamesLost(fileReader.nextInt());
          //  team.setRank(fileReader.nextInt());

          // while(j < 3)
          //  {
           //     Bowler bowler = new Bowler();
         //       bowler.setBowlerId(fileReader.nextInt());
           //     bowler.setFirstName(fileReader.nextLine());
           //     bowler.setLastName(fileReader.nextLine());
          //      bowler.setTotalGames(fileReader.nextInt());
           //     bowler.setTotalPins(fileReader.nextInt());

           //     team.setBowler(j, bowler);
           //     j++;
           // }   

           // j = 0;

          //  _teams[i] = team; 
          //  i++;
        //}

   }

   catch(IOException ex)
    {
        System.out.println("File not found... ");
   }
}

The file (Ignore the extra enters, as they were only there for formatting. This is only 2 iterations of teams.):

Uh... The enters didn't come out right. My bad. Should I upload the file elsewhere? — Xenorosth, Feb 27 '13 at 03:09
@Xenorosth Why wouldn't you just format it as code or in pre tags? — Dave Newton, Feb 27 '13 at 03:21

Because Scanner#nextInt doesn't consume newline characters, the newline character immediately after 1001 will be passed though to the nextLine statement and your team name will appear empty.

You need consume this character before reading the next line. You can use:

fileReader.nextLine(); // consume newline
team.setTeamName(fileReader.nextLine());
