LocalDate withDayOfYear() method in Java with Examples
The withDayOfYear() method of LocalDate class in Java returns a copy of this LocalDate with the day-of-year altered.
Syntax:
public LocalDate withDayOfYear(int dayOfYear)
Parameter: This method accepts a mandatory parameter dayOfYear which specifies the day-of-year to set in the result, from 1 to 365-366.

Below programs illustrate the LocalDate.withDayOfYear() method:
Program 1:
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
LocalDate dt1 = LocalDate.parse( "2018-12-07" );
LocalDate result = dt1.withDayOfYear( 01 );
System.out.println( "The date with day of year is: " + result);
}
}
|
Output:
The date with day of year is: 2018-01-01
Program 2:
import java.util.*;
import java.time.*;
import java.time.temporal.ChronoField;
public class GfG {
public static void main(String[] args)
{
try {
LocalDate dt1 = LocalDate.parse( "2018-12-07" );
LocalDate result = dt1.withDayOfYear( 370 );
System.out.println( "The date with month is: " + result);
}
catch (Exception e) {
System.out.println(e);
}
}
}
|
Output:
