        String s = "Hello World!!";
              
        try {
           // create new string writer
           sw = new StringWriter();
           
           // create new buffered writer
           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();
        }
     }
