 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.
 For example, the value "2nd October 2007 at 13:45.30.123456789" can be
 stored in a LocalDateTime.
 
This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.
The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely suitable. However, any application that makes use of historical dates, and requires them to be accurate will find the ISO-8601 approach unsuitable.
 This is a value-based
 class; programmers should treat instances that are
 equal as interchangeable and should not
 use instances for synchronization, or unpredictable behavior may
 occur. For example, in a future release, synchronization may fail.
 The equals method should be used for comparisons.
- Implementation Requirements:
- This class is immutable and thread-safe.
- Since:
- 1.8

withReturns an adjusted copy of this date-time.This returns a LocalDateTime, based on this one, with the date-time adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". Key date-time classes also implement theTemporalAdjusterinterface, such asMonthandMonthDay. The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.For example this code returns a date on the last day of July: import static java.time.Month.*; import static java.time.temporal.TemporalAdjusters.*; result = localDateTime.with(JULY).with(lastDayOfMonth()); The classes LocalDateandLocalTimeimplementTemporalAdjuster, thus this method can be used to change the date, time or offset:result = localDateTime.with(date); result = localDateTime.with(time); The result of this method is obtained by invoking the TemporalAdjuster.adjustInto(Temporal)method on the specified adjuster passingthisas the argument.This instance is immutable and unaffected by this method call. - Specified by:
- within interface- ChronoLocalDateTime<LocalDate>
- Specified by:
- within interface- Temporal
- Parameters:

This can be used to change any supported field, such as the year, month or day-of-month. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.In some cases, changing the specified field can cause the resulting date-time to become invalid, such as changing the month from 31st January to February would make the day-of-month invalid. In cases like this, the field is responsible for resolving the date. Typically it will choose the previous valid date, which would be the last valid day of February in this example. If the field is a ChronoFieldthen the adjustment is implemented here. Thesupported fieldswill behave as per the matching method onLocalDateorLocalTime. All otherChronoFieldinstances will throw anUnsupportedTemporalTypeException.If the field is not a ChronoField, then the result of this method is obtained by invokingTemporalField.adjustInto(Temporal, long)passingthisas the argument. In this case, the field determines whether and how to adjust the instant.This instance is immutable and unaffected by this method call. - Specified by:

untilCalculates the amount of time until another date-time in terms of the specified unit.This calculates the amount of time between two LocalDateTimeobjects in terms of a singleTemporalUnit. The start and end points arethisand the specified date-time. The result will be negative if the end is before the start. TheTemporalpassed to this method is converted to aLocalDateTimeusingfrom(TemporalAccessor). For example, the amount in days between two date-times can be calculated usingstartDateTime.until(endDateTime, DAYS).The calculation returns a whole number, representing the number of complete units between the two date-times. For example, the amount in months between 2012-06-15T00:00 and 2012-08-14T23:59 will only be one month as it is one minute short of two months. There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit.between(Temporal, Temporal):// these two lines are equivalent amount = start.until(end, MONTHS); amount = MONTHS.between(start, end); The choice should be made based on which makes the code more readable.The calculation is implemented in this method for ChronoUnit. The unitsNANOS,MICROS,MILLIS,SECONDS,MINUTES,HOURSandHALF_DAYS,DAYS,WEEKS,MONTHS,YEARS,DECADES,CENTURIES,MILLENNIAandERASare supported. OtherChronoUnitvalues will throw an exception.If the unit is not a ChronoUnit, then the result of this method is obtained by invokingTemporalUnit.between(Temporal, Temporal)passingthisas the first argument and the converted input temporal as the second argument.This instance is immutable and unaffected by this method call. - Specified by:
- untilin interface- Temporal
- Parameters:
- endExclusive- the end date, exclusive, which is converted to a- LocalDateTime, not null
- unit- the unit to measure the amount in, not null
- Returns:
- the amount of time between this date-time and the end date-time
- Throws:

atOffsetCombines this date-time with an offset to create anOffsetDateTime.This returns an OffsetDateTimeformed from this date-time at the specified offset. All possible combinations of date-time and offset are valid.- Parameters:
- offset- the offset to combine with, not null
- Returns:
- the offset date-time formed from this date-time and the specified offset, not null
 
- 
atZoneCombines this date-time with a time-zone to create aZonedDateTime.This returns a ZonedDateTimeformed from this date-time at the specified time-zone. The result will match this date-time as closely as possible. Time-zone rules, such as daylight savings, mean that not every local date-time is valid for the specified zone, thus the local date-time may be adjusted.The local date-time is resolved to a single instant on the time-line. This is achieved by finding a valid offset from UTC/Greenwich for the local date-time as defined by the rulesof the zone ID.In most cases, there is only one valid offset for a local date-time. In the case of an overlap, where clocks are set back, there are two valid offsets. This method uses the earlier offset typically corresponding to "summer". In the case of a gap, where clocks jump forward, there is no valid offset. Instead, the local date-time is adjusted to be later by the length of the gap. For a typical one hour daylight savings change, the local date-time will be moved one hour later into the offset typically corresponding to "summer". To obtain the later offset during an overlap, call ZonedDateTime.withLaterOffsetAtOverlap()on the result of this method. To throw an exception when there is a gap or overlap, useZonedDateTime.ofStrict(LocalDateTime, ZoneOffset, ZoneId).- Specified by:
- atZonein interface- ChronoLocalDateTime<LocalDate>
- Parameters:
- zone- the time-zone to use, not null
- Returns:
- the zoned date-time formed from this date-time, not null
 
- 
compareToCompares this date-time to another date-time.The comparison is primarily based on the date-time, from earliest to latest. It is "consistent with equals", as defined by Comparable.If all the date-times being compared are instances of LocalDateTime, then the comparison will be entirely based on the date-time. If some dates being compared are in different chronologies, then the chronology is also considered, seeChronoLocalDateTime.compareTo(java.time.chrono.ChronoLocalDateTime<?>).- Specified by:
