adjustInto(temporal: Temporal): Temporal
Adjusts the specified temporal object.
Adjusts the specified temporal object.
This adjusts the specified temporal object using the logic encapsulated in the implementing class. Examples might be an adjuster that sets the date avoiding weekends, or one that sets the date to the last day of the month.
There are two equivalent ways of using this method. The first is to invoke this method directly. The second is to use
Temporal#with(TemporalAdjuster)
:// these two lines are equivalent, but the second approach is recommended temporal = thisAdjuster.adjustInto(temporal); temporal = temporal.with(thisAdjuster);
It is recommended to use the second approach,with(TemporalAdjuster)
, as it is a lot clearer to read in code.Specification for implementors
The implementation must take the input object and adjust it. The implementation defines the logic of the adjustment and is responsible for documenting that logic. It may use any method on
Temporal
to query the temporal object and perform the adjustment. The returned object must have the same observable type as the input objectThe input object must not be altered. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable temporal objects.
The input temporal object may be in a calendar system other than ISO. Implementations may choose to document compatibility with other calendar systems, or reject non-ISO temporal objects by
querying the chronology
.This method may be called from multiple threads in parallel. It must be thread-safe when invoked.

def
compare(other: ChronoLocalDate): Int
Compares this date to another date, including the chronology.
Compares this date to another date, including the chronology.
The comparison is based first on the underlying time-line date, then on the chronology. It is "consistent with equals", as defined by
Comparable
.For example, the following is the comparator order:
2012-12-03 (ISO)
2012-12-04 (ISO)
2555-12-04 (ThaiBuddhist)
2012-12-05 (ISO)
Values #2 and #3 represent the same date on the time-line. When two values represent the same date, the chronology ID is compared to distinguish them. This step is needed to make the ordering "consistent with equals".
If all the date objects being compared are in the same chronology, then the additional chronology stage is not required and only the local date is used. To compare the dates of two
TemporalAccessor
instances, including dates in two different chronologies, useChronoField#EPOCH_DAY
as a comparator.- other

def
minus(amountToAdd: Long, unit: TemporalUnit): MinguoDate
Returns an object of the same type as this object with the specified period subtracted.
Returns an object of the same type as this object with the specified period subtracted.
This method returns a new object based on this one with the specified period subtracted. For example, on a
LocalDate
, this could be used to subtract a number of years, months or days. The returned object will have the same observable type as this object.In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st March, then subtracting one month would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.
If the implementation represents a date-time that has boundaries, such as
LocalTime
, then the permitted units must include the boundary unit, but no multiples of the boundary unit. For example,LocalTime
must acceptDAYS
but notWEEKS
orMONTHS
.Specification for implementors
Implementations must behave in a manor equivalent to the default method behavior.
Implementations must not alter either this object or the specified temporal object. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable implementations.

query[R](query: TemporalQuery[R]): R
Queries this date-time.
Queries this date-time.
This queries this date-time using the specified query strategy object.
Queries are a key tool for extracting information from date-times. They exists to externalize the process of querying, permitting different approaches, as per the strategy design pattern. Examples might be a query that checks if the date is the day before February 29th in a leap year, or calculates the number of days to your next birthday.
The most common query implementations are method references, such as
LocalDate::from
andZoneId::from
. Further implementations are onTemporalQueries
. Queries may also be defined by applications.Specification for implementors
Implementations of this method must behave as follows:
public <R> R query(TemporalQuery<R> type) { // only include an if statement if the implementation can return it if (query == TemporalQueries.zoneId()) return // the ZoneId if (query == TemporalQueries.chronology()) return // the Chrono if (query == TemporalQueries.precision()) return // the precision // call default method return super.query(query); }

Gets the range of valid values for the specified field.
Gets the range of valid values for the specified field.
All fields can be expressed as a

integer. This method returns an object that describes the valid range for that value. The value of this temporal object is used to enhance the accuracy of the returned range. If the date-time cannot return the range, because the field is unsupported or for some other reason, an exception will be thrown.Note that the result only describes the minimum and maximum valid values and it is important not to read too much into them. For example, there could be values within the range that are invalid for the field.
Specification for implementors
Implementations must check and handle all fields defined in
ChronoField
. If the field is supported, then the range of the field must be returned. If unsupported, then aDateTimeException
must be thrown.If the field is not a

until(endExclusive: Temporal, unit: TemporalUnit): Long
Calculates the period between this temporal and another temporal in terms of the specified unit.
Calculates the period between this temporal and another temporal in terms of the specified unit.
This calculates the period between two temporals in terms of a single unit. The start and end points are
this
and the specified temporal. The result will be negative if the end is before the start. For example, the period in hours between two temporal objects can be calculated usingstartTime.until(endTime, HOURS)
.The calculation returns a whole number, representing the number of complete units between the two temporals. For example, the period in hours between the times 11:30 and 13:29 will only be one hour as it is one minute short of two hours.
There are two equivalent ways of using this method. The first is to invoke this method directly. The second is to use
Temporal)
:// these two lines are equivalent between = thisUnit.between(start, end); between = start.until(end, thisUnit);
The choice should be made based on which makes the code more readable.For example, this method allows the number of days between two dates to be calculated:
val daysBetween: Long = DAYS.between(start, end); // or alternatively val daysBetween: Long = start.until(end, DAYS);
Specification for implementors
Implementations must begin by checking to ensure that the input temporal object is of the same observable type as the implementation. They must then perform the calculation for all instances of
ChronoUnit
. ADateTimeException
must be thrown forChronoUnit
instances that are unsupported.If the unit is not a
ChronoUnit
, then the result of this method is obtained by invokingTemporalUnit.between(Temporal, Temporal)
passingthis
as the first argument and the input temporal as the second argument.In summary, implementations must behave in a manner equivalent to this code:
// check input temporal is the same type as this class if (unit instanceof ChronoUnit) { // if unit is supported, then calculate and return result // else throw DateTimeException for unsupported units } return unit.between(this, endTemporal);
The target object must not be altered by this method.
