    Default newLine isn't working

    Hi, I'm encountering a slight problem where I'm getting an error for out.newLine();
    Here is the error:

    java.io.IOException: Stream closed
    	at java.io.BufferedWriter.ensureOpen(Unknown Source)
    	at java.io.BufferedWriter.write(Unknown Source)
    	at java.io.Writer.write(Unknown Source)

    	at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
    	at java.awt.EventDispatchThread.run(Unknown Source)
    The line is, as I mentioned, out.newLine();

    Here is some relevant code:

                              File rfile4 = new File(dir + "temp.txt");
    		          FileWriter writer = new FileWriter(dir + "temp.txt",true);
    		          BufferedWriter out = new BufferedWriter(writer);
                              pointsfile = "";
                              while(linenum > 1)
                              {
                                      out.newLine();
    			                                 out.write(pointsfile); 
    			                                 out.close();
                              }

    If you enter the while loop a second time, the stream has already been closed by a previous loop. linenum is not defined, but I presume you want your loop to go more than once. If so, move the out.close outside the while loop.

    while(linenum > 1)
                              {
                                      out.newLine();
                                                 out.write(pointsfile);
     
                              }
     out.close();
    Wait...copeg already got there first.



    Also, linenum I'm assuming means line number.
    How about also adding a condition to tell it to exit the while loop when you reach a blank line? That way it won't go on forever.

    Yes copeg solved it. And don't worry penguin, I didn't include all the code, linenum is the number of lines there are before I get to the line that I need to use and at the end of each time it goes through the loop, I make it decrease by 1. Thanks though.
