  public class CharArrayWriterDemo {
     public static void main(String[] args) {      
        String str = "Hello World!!";
        CharArrayWriter chw = null;
        CharArrayWriter chwd = null;   

        try {
           // create character array writer
           chw = new CharArrayWriter();

           // create destination character array writer
           chwd = new CharArrayWriter();

           // string to be written to writer
           chw.write(str);

           // write to destination array writer
           chw.writeTo(chwd);

           // print the destination buffer content as string
           System.out.println(chwd.toString());

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