Java LocalDate with() Method
Java with() method is used to get a new date by setting a new value of the specified field. It returns a copy of this date with the specified field set to a new value.
For example, we have a date 2012-10-12 then by specifying DAY_OF_MONTH value as 15, we get a new date 2012-10-15.
Temporal type can be specified with a ChronoField. The supported fields of ChronoField are as follows:
It takes two arguments first is Temporal type and second is long type. The syntax of the method is given.
Syntax
public LocalDate with(TemporalField field, long newValue)
Parameters:
field - the field to set in the result.
newValue - the new value of the field in the date.
Returns:
It returns a LocalDate based on this with the specified field.
Time for an Example:
Let's take an example to create a new date by setting a new value of a field. Here, we are using with() method to set new day of the date.
import java.time.LocalDate;
import java.time.temporal.ChronoField;
public class DateDemo {
public static void main(String[] args){
LocalDate localDate = LocalDate.of(2002, 01, 10);
System.out.println(localDate);
localDate = localDate.with(ChronoField.DAY_OF_MONTH, 15);
System.out.println("New Date : "+localDate);
}
}
2002-01-10
New Date : 2002-01-15
Time for another Example:
Let's take an another example to understand the with() method. Here, we are setting a new value of date by specifying the DAY_OF_YEAR value.
import java.time.LocalDate;
import java.time.temporal.ChronoField;
public class DateDemo {
public static void main(String[] args){
LocalDate localDate = LocalDate.of(2002, 01, 10);
System.out.println(localDate);
localDate = localDate.with(ChronoField.DAY_OF_YEAR, 35);
System.out.println("New Date : "+localDate);
}
}
2002-01-10
New Date : 2002-02-04
