      char[] ch = {'A','B','C','D','E'};
      CharArrayWriter chw = null;
            
      try{
         // create character array writer
         chw = new CharArrayWriter();
         System.out.println("off = 3; len=2");
         
         // write character buffer to the writer
         chw.write(ch, 3, 2);

         System.out.print(str);
         
      }catch(Exception e){
         
         // for any error
         e.printStackTrace();
      }finally{
         
         // releases all system resources from writer
         if(chw!=null)
            chw.close();
      }
   }
}

Let us compile and run the above program, this will produce the following result:
