LocalDateTime

public final class LocalDateTime extends Object
implements Temporal TemporalAdjuster ChronoLocalDateTime<LocalDate> Serializable

A date-time without a time-zone in the ISO-8601 calendar system, such as 2007-12-03T10:15:30.

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.

Fields

public static final LocalDateTime MAX

The maximum supported LocalDateTime, '+999999999-12-31T23:59:59.999999999'. This is the local date-time just before midnight at the end of the maximum date. This combines LocalDate.MAX and LocalTime.MAX. This could be used by an application as a "far future" date-time.

public static final LocalDateTime MIN

The minimum supported LocalDateTime, '-999999999-01-01T00:00:00'. This is the local date-time of midnight at the start of the minimum date. This combines LocalDate.MIN and LocalTime.MIN. This could be used by an application as a "far past" date-time.

Public Methods

public Temporal adjustInto (Temporal temporal)

Adjusts the specified temporal object to have the same date and time as this object.

This returns a temporal object of the same observable type as the input with the date and time changed to be the same as this.

The adjustment is equivalent to using Temporal.with(TemporalField, long) twice, passing ChronoField.EPOCH_DAY and ChronoField.NANO_OF_DAY as the fields.

In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):

   // these two lines are equivalent, but the second approach is recommended
   temporal = thisLocalDateTime.adjustInto(temporal);
   temporal = temporal.with(thisLocalDateTime);

This instance is immutable and unaffected by this method call.

Parameters

temporal	the target object to be adjusted, not null

Returns

the adjusted object, not null

Throws

DateTimeException	if unable to make the adjustment
ArithmeticException	if numeric overflow occurs

public OffsetDateTime atOffset (ZoneOffset offset)

Combines this date-time with an offset to create an OffsetDateTime.

This returns an OffsetDateTime formed 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

public ZonedDateTime atZone (ZoneId zone)

Combines this date-time with a time-zone to create a ZonedDateTime.

This returns a ZonedDateTime formed 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 rules of 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, use ZonedDateTime.ofStrict(LocalDateTime, ZoneOffset, ZoneId).

Parameters

zone	the time-zone to use, not null

Returns

the zoned date-time formed from this date-time, not null

public int compareTo (ChronoLocalDateTime<?> other)

Compares 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, see Comparable.compareTo(T).

Parameters

other	the other date-time to compare to, not null

Returns

the comparator value, negative if less, positive if greater

public boolean equals (Object obj)

Checks if this date-time is equal to another date-time.

Compares this LocalDateTime with another ensuring that the date-time is the same. Only objects of type LocalDateTime are compared, other types return false.

Parameters

obj	the object to check, null returns false

Returns

true if this is equal to the other date-time

public String format (DateTimeFormatter formatter)

Formats this date-time using the specified formatter.

This date-time will be passed to the formatter to produce a string.

Parameters

formatter	the formatter to use, not null

Returns

the formatted date-time string, not null

Throws

DateTimeException	if an error occurs during printing

public static LocalDateTime from (TemporalAccessor temporal)

Obtains an instance of LocalDateTime from a temporal object.

This obtains a local date-time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of LocalDateTime.

The conversion extracts and combines the LocalDate and the LocalTime from the temporal object. Implementations are permitted to perform optimizations such as accessing those fields that are equivalent to the relevant objects.

This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, LocalDateTime::from.

Parameters

temporal	the temporal object to convert, not null

Returns

the local date-time, not null

Throws

DateTimeException	if unable to convert to a `LocalDateTime`

public int get (TemporalField field)

Gets the value of the specified field from this date-time as an int.

This queries this date-time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date-time, except NANO_OF_DAY, MICRO_OF_DAY, EPOCH_DAY and PROLEPTIC_MONTH which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters

field	the field to get, not null

Returns

the value for the field

Throws

DateTimeException	if a value for the field cannot be obtained or the value is outside the range of valid values for the field
UnsupportedTemporalTypeException	if the field is not supported or the range of values exceeds an `int`
ArithmeticException	if numeric overflow occurs

public int getDayOfMonth ()

Gets the day-of-month field.

This method returns the primitive int value for the day-of-month.

Returns

the day-of-month, from 1 to 31

public DayOfWeek getDayOfWeek ()

Gets the day-of-week field, which is an enum DayOfWeek.

This method returns the enum DayOfWeek for the day-of-week. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.

Additional information can be obtained from the DayOfWeek. This includes textual names of the values.

Returns

the day-of-week, not null

public int getDayOfYear ()

Gets the day-of-year field.

This method returns the primitive int value for the day-of-year.

Returns

the day-of-year, from 1 to 365, or 366 in a leap year

public int getHour ()

Gets the hour-of-day field.

Returns

the hour-of-day, from 0 to 23

public long getLong (TemporalField field)

Gets the value of the specified field from this date-time as a long.

This queries this date-time for the value of the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date-time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

Parameters

field	the field to get, not null

Returns

the value for the field

Throws

DateTimeException	if a value for the field cannot be obtained
UnsupportedTemporalTypeException	if the field is not supported
ArithmeticException	if numeric overflow occurs

public int getMinute ()

Gets the minute-of-hour field.

Returns

the minute-of-hour, from 0 to 59

public Month getMonth ()

Gets the month-of-year field using the Month enum.

This method returns the enum Month for the month. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.

Returns

the month-of-year, not null

public int getMonthValue ()

Gets the month-of-year field from 1 to 12.

This method returns the month as an int from 1 to 12. Application code is frequently clearer if the enum Month is used by calling getMonth().

Returns

the month-of-year, from 1 to 12

public int getNano ()

Gets the nano-of-second field.

Returns

the nano-of-second, from 0 to 999,999,999

public int getSecond ()

Gets the second-of-minute field.

Returns

the second-of-minute, from 0 to 59

public int getYear ()

Gets the year field.

This method returns the primitive int value for the year.

The year returned by this method is proleptic as per get(YEAR). To obtain the year-of-era, use get(YEAR_OF_ERA).

Returns

the year, from MIN_YEAR to MAX_YEAR

public int hashCode ()

A hash code for this date-time.

Returns

a suitable hash code

public boolean isAfter (ChronoLocalDateTime<?> other)

Checks if this date-time is after the specified date-time.

This checks to see if this date-time represents a point on the local time-line after the other date-time.

   LocalDate a = LocalDateTime.of(2012, 6, 30, 12, 00);
   LocalDate b = LocalDateTime.of(2012, 7, 1, 12, 00);
   a.isAfter(b) == false
   a.isAfter(a) == false
   b.isAfter(a) == true

This method only considers the position of the two date-times on the local time-line. It does not take into account the chronology, or calendar system. This is different from the comparison in compareTo(ChronoLocalDateTime), but is the same approach as ChronoLocalDateTime.timeLineOrder().

Parameters

other	the other date-time to compare to, not null

Returns

true if this date-time is after the specified date-time

public boolean isBefore (ChronoLocalDateTime<?> other)

Checks if this date-time is before the specified date-time.

This checks to see if this date-time represents a point on the local time-line before the other date-time.

   LocalDate a = LocalDateTime.of(2012, 6, 30, 12, 00);
   LocalDate b = LocalDateTime.of(2012, 7, 1, 12, 00);
   a.isBefore(b) == true
   a.isBefore(a) == false
   b.isBefore(a) == false

Parameters

other	the other date-time to compare to, not null

Returns

true if this date-time is before the specified date-time

public boolean isEqual (ChronoLocalDateTime<?> other)

Checks if this date-time is equal to the specified date-time.

This checks to see if this date-time represents the same point on the local time-line as the other date-time.

   LocalDate a = LocalDateTime.of(2012, 6, 30, 12, 00);
   LocalDate b = LocalDateTime.of(2012, 7, 1, 12, 00);
   a.isEqual(b) == false
   a.isEqual(a) == true
   b.isEqual(a) == false

Parameters

other	the other date-time to compare to, not null

Returns

true if this date-time is equal to the specified date-time

public boolean isSupported (TemporalUnit unit)

Checks if the specified unit is supported.

This checks if the specified unit can be added to, or subtracted from, this date-time. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.

If the unit is a ChronoUnit then the query is implemented here. The supported units are:

NANOS
MICROS
MILLIS
SECONDS
MINUTES
HOURS
HALF_DAYS
DAYS
WEEKS
MONTHS
YEARS
DECADES
CENTURIES
MILLENNIA
ERAS

All other ChronoUnit instances will return false.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.

Parameters

unit	the unit to check, null returns false

Returns

true if the unit can be added/subtracted, false if not

public boolean isSupported (TemporalField field)

Checks if the specified field is supported.

This checks if this date-time can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.

NANO_OF_SECOND
NANO_OF_DAY
MICRO_OF_SECOND
MICRO_OF_DAY
MILLI_OF_SECOND
MILLI_OF_DAY
