常规方法格式化时间(SimpleDateFormat)通常来讲，在Java中格式化时间，可以使用SimpleDateFormat类。以下是一个示例代码：在上面的示例中，我们使用SimpleDateFormat类来格式化时间。我们获取当前时间now，然后创建一个SimpleDateFormat对象sdf，并指定日期格式为"yyyy-MM-dd HH:mm:ss"。最后，我们使用sdf.format(now)方法...
DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.LONG); String formattedDateTime = formatter.format(LocalDateTime.now()); System.out.println("本地化时间:" + formattedDateTime); } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 输出结果将会...

SimpleDateFormatallows you to start by choosing any user-defined patterns for date-time formatting. However, you are encouraged to create a date-time formatter with eithergetTimeInstance,getDateInstance, orgetDateTimeInstanceinDateFormat. Each of these class methods can return a date/time formatter ini...
