         // closes the stream
         chw.close();
         
         // append character sequence to the writer
         chw.append(csq);
         
         // prints out the character sequences
         System.out.println(chw.toString());
         
      } catch(Exception e) {
         // for any error
         e.printStackTrace();
      } finally {
