public class Demo5 {
    public static void main(String[] args) throws ParseException {
        Date date =new Date();
//        SimpleDateFormat sdf = new SimpleDateFormat();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 hh:mm:ss");
        String s = sdf.format(date);
        System.out.println(s);

        String ss ="2025-02-06 6:25:11";
        SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
        Date date2 = sdf2.parse(ss);
        System.out.println(date2);
