Convert LocalDateTime to Date type

//LocalDateTime is a date processing class, which can be set to year, month, day, hour, minute and second, which is equivalent to LocalDate+LocalTime//Get the current time through LocalDateTime.now(), specific to the year, month, day, hour, minute and secondLocalDateTime localDateTime = LocalDateTime.now();//Zoneld is used to identify the conversion rule between Instant and LocalDateTime, and is also the time zone ID//Get the system default time zone through the systemDefault of ZoneIdZoneId zoneId = ZoneId.systemDefault();//LocalDateTime can only display the local date and time, no time zone//ZoneIdDateTime to identify a date and time with a time zone//ZonedDateTime is equivalent to LocalDateTime+ZoneId//Convert LocalDateTime to ZoneDateTime through atZone(new ZoneID) of LocalDateTimeZonedDateTime zonedDateTime =localDateTime.atZone(zoneId);//The Instant class is used to record the timestamp of the event in the application// that is, convert the time into a moment//ZonedDateTime.toInstant is used to convert ZonedDateTime to Instant typeInstant instant = zonedDateTime.toInstant();//Use the Date.from(new instant) method to change to Date type, which represents the same point on the time axis as the passed instant.Date date = Date.from(instant);System.out.println(date);

The corresponding ZoneId, ZonedDateTime, and Instant have many methods to get the time in different situations
