Adjusts the specified temporal object to have this day-of-week.
Adjusts the specified temporal object to have this day-of-week.
This returns a temporal object of the same observable type as the input with the day-of-week changed to be the same as this.
The adjustment is equivalent to using long)
passing ChronoField#DAY_OF_WEEK
as the field.
Note that this adjusts forwards or backwards within a Monday to Sunday week.
See WeekFields#dayOfWeek
for localized week start days.
See TemporalAdjusters
for other adjusters
with more control, such as next(MONDAY)
.
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 = thisDayOfWeek.adjustInto(temporal); temporal = temporal.with(thisDayOfWeek);
For example, given a date that is a Wednesday, the following are output:
dateOnWed.with(MONDAY); // two days earlier dateOnWed.with(TUESDAY); // one day earlier dateOnWed.with(WEDNESDAY); // same date dateOnWed.with(THURSDAY); // one day later dateOnWed.with(FRIDAY); // two days later dateOnWed.with(SATURDAY); // three days later dateOnWed.with(SUNDAY); // four days later
This instance is immutable and unaffected by this method call.

Gets the value of the specified field from this day-of-week as an int
.
Gets the value of the specified field from this day-of-week as an int
.
This queries this day-of-week for the value for 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 DAY_OF_WEEK
then the
value of the day-of-week, from 1 to 7, will be returned.
All other ChronoField
instances will throw a DateTimeException
.
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.

Gets the textual representation, such as 'Mon' or 'Friday'.
Gets the textual representation, such as 'Mon' or 'Friday'.
This returns the textual name used to identify the day-of-week. The parameters control the length of the returned text and the locale.
If no textual mapping is found then the numeric value
is returned.

Checks if the specified field is supported.
Checks if the specified field is supported.
This checks if this day-of-week can be queried for the specified field.
If false, then calling the range
and
get
methods will throw an exception.
If the field is DAY_OF_WEEK
then
this method returns true.
All other ChronoField
instances will return false.
If the field is not a ChronoField

is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor)
passing this
as the argument.
Whether the field is supported is determined by the field.

Gets the range of valid values for the specified field.
Gets the range of valid values for the specified field.
The range object expresses the minimum and maximum valid values for a field. This day-of-week is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.
If the field is DAY_OF_WEEK
then the
range of the day-of-week, from 1 to 7, will be returned.
