         // for each character in character array
         for (char c : ch)
         {
         
            // print character
            System.out.println(c);
         }     
      }catch(Exception e){
         
         // for any error
         e.printStackTrace();
      }finally{
         
         // releases all system resources from writer
         if(chw!=null)
            chw.close();
