Hi Sam,

The cool thing about many of the Reader and Stream objects in the
java.io package is that you can chain them together for the desired
results. Try something like this:

  public static List<Integer> getIntegersFromFile(
      String fileName) throws IOException {
    StringWriter writer = new StringWriter();
    BufferedReader reader = new BufferedReader(
        new FileReader(fileName));
    for (String line = reader.readLine(); line != null; line = reader
        .readLine()) {
      writer.write(line + " ");
    }
    StringTokenizer tokens = new StringTokenizer(writer
        .toString());
    List<Integer> list = new ArrayList<Integer>();
    while (tokens.hasMoreTokens()) {
      String str = tokens.nextToken();
      try {
        list.add(new Integer(str));
      } catch (NumberFormatException e) {
        System.out.println("Error '" + str
            + "' is not an integer.");
      }
    }
    // If you wanted an int array
    // int[] array = new int[list.size()];
    // for( int i = 0; i < array.length; i++){
    //   array[i] = list.get(i);
    // }
    return list;
  }

Cheers,

Dan Andrews
