Adjusts the specified temporal object to have this month-of-year.
Adjusts the specified temporal object to have this month-of-year.
This returns a temporal object of the same observable type as the input with the month-of-year changed to be the same as this.
The adjustment is equivalent to using long)
passing ChronoField#MONTH_OF_YEAR
as the field.
If the specified temporal object does not use the ISO calendar system then
a DateTimeException
is thrown.
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 = thisMonth.adjustInto(temporal); temporal = temporal.with(thisMonth);
For example, given a date in May, the following are output:
dateInMay.with(JANUARY); // four months earlier dateInMay.with(APRIL); // one months earlier dateInMay.with(MAY); // same date dateInMay.with(JUNE); // one month later dateInMay.with(DECEMBER); // seven months later
This instance is immutable and unaffected by this method call.

Gets the value of the specified field from this month-of-year as an int
.
Gets the value of the specified field from this month-of-year as an int
.
This queries this month 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 MONTH_OF_YEAR
then the
value of the month-of-year, from 1 to 12, will be returned.
All other ChronoField
instances will throw a DateTimeException
.
If the field is not a ChronoField

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.

Checks if the specified field is supported.
Checks if the specified field is supported.
This checks if this month-of-year can be queried for the specified field.
If false, then calling the range

get
methods will throw an exception.
If the field is MONTH_OF_YEAR
then
this method returns true.
All other ChronoField
instances will return false.
