I would like to create a copy java.time.LocalDateTime but it does not have clone() method.
What I do is the following:
long epochMilli = Instant.now().toEpochMilli(); LocalDateTime createDate = LocalDateTime.ofInstant(Instant.ofEpochMilli(epochMilli), ZoneId.systemDefault()); LocalDateTime modificationDate = LocalDateTime.ofInstant(Instant.ofEpochMilli(epochMilli), ZoneId.systemDefault()); Is there an easyest way to create two LocalDateTime objects with the exact same date-time value?

getDays() + " days " + time[0] + " hours " + time[1] + " minutes " + time[2] + " seconds.");
LocalDateTime is an immutable date-time object that represents a date-time, often viewed as year-month-day-hour-minute-second. Other date and time fields, such as day-of-year, day-of-week and week-of-year, can also be accessed. Time is represented to nanosecond precision.
Instant and LocalDateTime are two entirely different animals: One represents a moment, the other does not. Instant represents a moment, a specific point in the timeline. LocalDateTime represents a date and a time-of-day. But lacking a time zone or offset-from-UTC, this class cannot represent a moment.
Because LocalDateTime is immutable, you can simply reference the same object:
LocalDateTime createDate = LocalDateTime.now(); LocalDateTime modificationDate = createDate; Since it's immutable, you can do it this way:
LocalDateTime copy = createDate.plusHours(0); System.out.println(createDate.equals(copy)); // true plusHours doc:
Returns a copy of this LocalDateTime with the specified number of hours added. This instance is immutable and unaffected by this method call.
