如何每天以其名称作为当前日期创建新目录

Question

Date dir = new java.util.Date(System.currentTimeMillis());String baseDir = "/home/gaurav/usr/logs/ESBegin/";String newDir = createDateBasedDirectory(baseDir, dir);Logger logger = Logger.getLogger("MyLog1");  FileHandler fh;  try {      // This block configure the logger with handler and formatter      fh = new FileHandler(newDir+"/data.log");      logger.addHandler(fh);    SimpleFormatter formatter = new SimpleFormatter();      fh.setFormatter(formatter);      // the following statement is used to log any messages      logger.info(stringifiedJson);  } catch (SecurityException e) {      e.printStackTrace();  } catch (IOException e) {      e.printStackTrace();  }  这将创建一个今天的文件夹，但是我想为每天创建一个新文件夹并将日志文件存储在新文件夹中....意味着每天的文件夹必须具有当天的日志文件，我具有以下创建文件夹的方法 public static String createDateBasedDirectory(String baseDirectory, Date argDate) {        String newDir = null;        if (baseDirectory != null && argDate != null) {            try {                String format = "yyyy-MM-dd";                DateFormat dateFormatter = new SimpleDateFormat(format);                String date = dateFormatter.format(argDate);                File f = new File(baseDirectory);                File files[] = f.listFiles();                String dir = null;                int baseDirLength = baseDirectory.length();                int checkingLength = baseDirLength + format.length() + 3;                int maxSeqNo = 0;                for (int i = 0; i < files.length; i++) {                    if (files[i].isDirectory()) {                        dir = files[i].toString();                        if (dir.length() == checkingLength) {                            String existingDirDate = dir.substring(baseDirLength, baseDirLength + 10);如果要每天创建一个新文件夹，我应该更改什么？
