         chw = new CharArrayWriter();
         // declare character sequence
         CharSequence csq = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
         // append character sequence to the writer
         chw.append(csq);
         // flush
         chw.flush();
         // prints out the character sequences
         System.out.println(chw.toString());
      } catch(Exception e) {
         // for any error
         e.printStackTrace();
      } finally {
         // releases all system resources from writer
         if(chw!=null)
            chw.close();
      }
