TemporalAdjusters firstDayOfYear() method in Java with Examples
The firstDayOfYear() method of a TemporalAdjusters class is used to return the “first day of the year” TemporalAdjuster object, which returns a new Date object set to the first day of the year.
Syntax:
public static TemporalAdjuster firstDayOfYear()
Parameters: This method accepts nothing.
Return value: This method returns the first day of the year adjuster, not null.
Below programs illustrate the TemporalAdjusters.firstDayOfYear() method:
Program 1:
import java.time.LocalDate;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
TemporalAdjuster temporalAdjuster
= TemporalAdjusters.firstDayOfYear();
LocalDate localDate
= LocalDate.of( 2012 , 05 , 31 );
LocalDate firstDayOfYear
= localDate.with(temporalAdjuster);
System.out.println( "First day of the "
+ "year for localdate "
+ localDate + ": "
+ firstDayOfYear);
}
}
|
Output:
First day of the year for localdate 2012-05-31: 2012-01-01
Program 2:
import java.time.LocalDate;
import java.time.temporal.*;
public class GFG {
public static void main(String[] args)
{
TemporalAdjuster temporalAdjuster
= TemporalAdjusters.firstDayOfYear();
LocalDate localDate
= LocalDate.of( 2000 , 12 , 21 );
LocalDate firstDayOfYear
= localDate.with(temporalAdjuster);
System.out.println( "First day of the "
+ "year for localdate "
+ localDate + ": "
+ firstDayOfYear);
}
}
|
Output:
First day of the year for localdate 2000-12-21: 2000-01-01
