  public static void main(String[] args) throws IOException {

    int size = 0;

    byte[] bs = { 65, 66, 67, 68, 69 };

    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    for (byte b : bs) {
      baos.write(b);

      String str = baos.toString();
      size = baos.size();

      System.out.print(size + ":");
      System.out.println(str);
