with
public Temporal with(TemporalAdjuster adjuster)
Description copied from interface:Temporal
Returns an adjusted object of the same type as this object with the adjustment made.This adjusts this date-time according to the rules of the specified adjuster. 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". The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.Some example code indicating how and why this method is used:
date = date.with(Month.JULY); // most key classes implement TemporalAdjuster date = date.with(lastDayOfMonth()); // static import from TemporalAdjusters date = date.with(next(WEDNESDAY)); // static import from TemporalAdjusters and DayOfWeek
Specification for implementors
Implementations must not alter either this object. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable implementations.
-
plus
public Temporal plus(TemporalAmount amount)
Description copied from interface:Temporal
Returns an object of the same type as this object with an amount added.This adjusts this temporal, adding according to the rules of the specified amount. The amount is typically a
Period
but may be any other type implementing theTemporalAmount
interface, such asDuration
.Some example code indicating how and why this method is used:
date = date.plus(period); // add a Period instance date = date.plus(duration); // add a Duration instance date = date.plus(workingDays(6)); // example user-written workingDays method
Note that calling
plus
followed byminus
is not guaranteed to return the same date-time.Specification for implementors
Implementations must not alter either this object. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable implementations.
-
minus
public Temporal minus(TemporalAmount amount)
Description copied from interface:Temporal
Returns an object of the same type as this object with an amount subtracted.This adjusts this temporal, subtracting according to the rules of the specified amount. The amount is typically a
Period
but may be any other type implementing theTemporalAmount
interface, such asDuration
.Some example code indicating how and why this method is used:
date = date.minus(period); // subtract a Period instance date = date.minus(duration); // subtract a Duration instance date = date.minus(workingDays(6)); // example user-written workingDays method
Note that calling
plus
followed byminus
is not guaranteed to return the same date-time.Specification for implementors
Implementations must not alter either this object. Instead, an adjusted copy of the original must be returned. This provides equivalent, safe behavior for immutable and mutable implementations.
-
minus
public Temporal minus(long amountToSubtract, TemporalUnit unit)
Description copied from interface:Temporal
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.
