    StringReader sr = new StringReader(s);

    // create new buffered reader
    BufferedReader br = new BufferedReader(sr);

    // Destination source is created
    CharBuffer target = CharBuffer.allocate(s.length());

    // ready is invoked to test if character stream is ready
    if (br.ready()) {
      br.read(target);
