  import java.io.CharArrayWriter;

  public class CharArrayWriterDemo {
     public static void main(String[] args) {      
        CharArrayWriter chw = null;

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

           String str = "Hello World!!";

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

           // get array of character from the writer
           char[] ch = chw.toCharArray();

           // 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();
        }
     }
