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

         // 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();
