      buffer.clear();
    }
  }

  private static void drainBuffer(CharBuffer buffer) {
    while (buffer.hasRemaining()) {
      System.out.print(buffer.get());
    }
    System.out.println("");
  }

  private static boolean fillBuffer(CharBuffer buffer) {
    if (index >= strings.length) {
      return (false);
    }
    String string = strings[index++];
    for (int i = 0; i < string.length(); i++) {
      buffer.put(string.charAt(i));
    }
