            bw = new BufferedWriter(sw);

            // write string sequence to buffered writer
            bw.write(s, 0, 5);

            // write new line to the buffered writer
            bw.newLine();

            // write the next string sequence to buffered writer
            bw.write(s, 6, s.length()-6);

            // releases all bytes to the underlying stream
            bw.flush();

            // print
            System.out.print(sw.getBuffer());

        } catch(Exception e) {
            // if any I/O error occurs
            e.printStackTrace();
        } finally {
            // releases system resources from the streams
            if(sw!=null)
                sw.close();
            if(bw!=null)
                bw.close();
