We can utilize theofLocalizedDate(),ofLocalizedTime(), andofLocalizedDateTime()methods to get the specific date-time parts formatted withLocalerules. Locale.setDefault(Locale.GERMANY);Stringld=LocalDate.now().format(DateTimeFormatter.ofLocalizedDate(FormatStyle.LONG));System.out.println(ld);// 14. ...

After that, we can use the methods on the LocalDateTime object to separate the date and time components. Let’s look at an example: String dateTimeStr = "2024-07-04 11:15:24"; DateTimeFormatter format = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss", Locale.ENGLISH); DateTimeFormatter ...
使用java.time类库:在新的 Java 版本中,优先使用java.time类库,如LocalDateTime、ZonedDateTime、Duration等,以替代旧的日期时间类,如Date和SimpleDateFormat。java.time类库更现代、更强大,避免了许多传统类的问题。 避免使用java.util.Date:避免在新代码中使用Date类,因为它存在线程安全性问题和时区问题。如果必须与旧...
long end = System.currentTimeMillis(); System.out.println(); System.out.println("执行时间:"+(end - start)); } 1. 2. 3. 4. 5. 6. 7. 8. 9. 3.util.Date util.Date是java最初的日期时间用法,因为执行的速度很快,所以不一定先new的Date就一定比后new的Date小,二者还可能是一样的。
