1. A string that converts LocalDateTime to a custom time format

Public static String getDateTimeAsString (LocalDateTime localDateTime, String format) {DateTimeFormatter formatter = DateTimeFormatter.ofPattern (format); return localDateTime.format (formatter);}

two。 Convert timestamp of type long to LocalDateTime

Public static LocalDateTime getDateTimeOfTimestamp (long timestamp) {Instant instant = Instant.ofEpochMilli (timestamp); ZoneId zone = ZoneId.systemDefault (); return LocalDateTime.ofInstant (instant, zone);}

3. Convert LocalDateTime to timestamp of type long

Public static long getTimestampOfDateTime (LocalDateTime localDateTime) {ZoneId zone = ZoneId.systemDefault (); Instant instant = localDateTime.atZone (zone). ToInstant (); return instant.toEpochMilli ();}

4. Convert a time string to a LocalDateTime with a custom time format

Public static LocalDateTime parseStringToDateTime (String time, String format) {DateTimeFormatter df = DateTimeFormatter.ofPattern (format); return LocalDateTime.parse (time, df);}
