    Default BufferedReader

    Hi, i need your help...

    private static LinkedList lines = new LinkedList();
    ...
    public static void read() throws IOException{
            try {
            String sCurrentLine;
            BufferedReader br =
                 new BufferedReader(new FileReader("forum.log"));
            String[] line = null;
            while ((sCurrentLine = br.readLine()) != null) {
                    System.out.println(sCurrentLine);
                   line = sCurrentLine.split(",");
                   lines.add(line);
             }
            br.close();
            lines.toArray(new String[lines.size()]);
            for(int i=0; i<=lines.size(); i++)
                System.out.println(lines.get(i));
        } catch (FileNotFoundException e) {
     
          e.printStackTrace();
     
        } catch (IOException e) {
     
          e.printStackTrace();
     
        }
     
      }

    In the linked list lines i want to save the words separated by "," but it gives me some exceptions and im not sure if that code does that...

    Default Re: BufferedReader

    My guess might be this line:
    lines.add(line);

    Can you add an array to a LinkedList? I know there is an addAll(Collection<? extends E> c) method, but I don't think the standard add(E e) method lets you send it a String[]. Not sure though.

    Continuing on that thought, this line:
    lines.toArray(new String[lines.size()]);
    will do nothing, since the toArray(T[] a) method returns a <T> T[], which you do not capture.
