The withYear() method of LocalDateTime class in Java is used to get a copy of this LocalDateTime with the year changed to the year passed as the parameter to this method. The remaining values of this LocalDateTime remains the same.
Syntax:
public LocalDateTime withYear(int year)
Parameter: This method accepts a single mandatory parameter year which specifies the year to be set in the resultant LocalDateTime instance. The value of this year can range from MIN_YEAR to MAX_YEAR.
Returns: The function returns a LocalDateTime instance with the year changed to the year passed as the parameter to this method. The remaining values of this LocalDateTime remains the same.
Exceptions: The function throws a DateTimeException if the year value is invalid.
Below programs illustrate the LocalDateTime.withYear() method:
Program 1:
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
LocalDateTime dt = LocalDateTime.now();
System.out.println("Original LocalDateTime: "
+ dt.toString());
System.out.println("New LocalDateTime: "
+ dt.withYear(1998));
}
}
|
Output:
Original LocalDateTime: 2018-11-30T10:35:17.833
New LocalDateTime: 1998-11-30T10:35:17.833
Program 2:
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
LocalDateTime dt
= LocalDateTime
.parse("2015-04-06T10:15:30");
System.out.println("Original LocalDateTime: "
+ dt.toString());
System.out.println("New LocalDateTime: "
+ dt.withYear(20129));
}
}

Original LocalDateTime: 2015-04-06T10:15:30
