### Question:
BeetlUtil { public static boolean checkNameing(String str) { char[] commonArray = new char[str.length()]; int len = 0; if (str == null || (len = str.length()) == 0) { return false; } str.getChars(0, len, commonArray, 0); int index = 0; char word = commonArray[index++]; if (word >= 46 && word <= 57) setLog(1, word); else if (commonArray[len - 1] == 46) setLog(len, 46); else while (true) { if (word < 36 || word > 122 || chars[word - 36] == 0) { setLog(index + 1, word); return false; } if (index == len) return true; word = commonArray[index++]; } return false; }  static boolean isOutsideOfRoot(String child); static String getRelPath(String siblings, String resourceId); static Writer getWriterByByteWriter(ByteWriter byteWriter); static void setWebroot(String webroot); static String getWebRoot(); static boolean checkNameing(String str); static int[] getLog(); static String reportChineseTokenError(String msg); static RuntimeException throwCastException(ClassCastException ex,GroupTemplate gt); static void autoFileFunctionRegister(GroupTemplate gt,File funtionRoot, String ns, String path,String functionSuffix); static String getParameterDescription(Class[] types);  }### Answer:
