DayOfWeek from() method in Java with Examples
The from() method of java.time.DayOfWeek is an in-built function in Java which takes a TemporalAccessor defining a date and returns an instance of DayOfWeek corresponding to that date. A TemporalAccessor represents an arbitrary set of date and time information, which this method converts to an instance of DayOfWeek corresponding to that date.
Method Declaration:
public static DayOfWeek from(TemporalAccessor temporal)
Syntax:
DayOfWeek dayOfWeekObject = DayOfWeek.from(TemporalAccessor temporal)
Parameters: This method takes temporal as parameter where:
temporal – is a TemporalAccessor which represents a date.
dayOfWeekObject – is an instance of DayOfWeek.
Return Value: The function returns an instance of DayOfWeek corresponding to the date specified by temporal
Below programs illustrate the above method:
Program 1:
import java.time.*;
import java.time.DayOfWeek;
class DayOfWeekExample {
public static void main(String[] args)
{
LocalDate localDate
= LocalDate.of( 1997 , Month.AUGUST, 15 );
DayOfWeek dayOfWeek
= DayOfWeek.from(localDate);
System.out.println( "Day of the Week on "
+ localDate + " - "
+ dayOfWeek.name());
}
}
|
Output:
Day of the Week on 1997-08-15 - FRIDAY
Program 2:
import java.time.*;
class DayOfWeekExample {
public static void main(String[] args)
{
LocalDate localDate
= LocalDate.of( 2015 , Month.JULY, 13 );
DayOfWeek dayOfWeek
= DayOfWeek.from(localDate);
System.out.println( "Day of the Week on "
+ localDate + " - "
+ dayOfWeek.name());
}
}
|
Output:
Day of the Week on 2015-07-13 - MONDAY
