ChronoLocalDate with(TemporalAdjuster) Method in Java with Examples

with(TemporalAdjuster adjuster) method of the ChronoLocalDate interface used to adjusted this date-time using TemporalAdjuster passed as parameter and after adjustment returns the copy of adjusted date-time.The adjustment takes place using the specified adjuster strategy object. This instance of ChronoLocalDate is immutable and unaffected by this method call.

Syntax:

public ChronoLocalDate with(TemporalAdjuster adjuster)

Parameters: This method accepts adjuster as parameter which is the adjuster to use.

Return value: This method returns a ChronoLocalDate based on this with the adjustment made.

Exception: This method throws following Exceptions:

• DateTimeException – if the adjustment cannot be made.
• ArithmeticException – if numeric overflow occurs.

Below programs illustrate the with() method:

Program 1:

// Java program to demonstrate
// ChronoLocalDate.with() method

import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a LocalDate object
        ChronoLocalDate local
            = LocalDate.parse(
                "2018-12-06");

        // print instance
        System.out.println("ChronoLocalDate before"
                           + " adjustment: "
                           + local);

        // apply with method of LocalDate class
        ChronoLocalDate updatedlocal
            = local.with(Month.MARCH)
                  .with(TemporalAdjusters
                            .lastDayOfMonth());

        // print instance
        System.out.println("ChronoLocalDate after"
                           + " adjustment: "
                           + updatedlocal);
    }
}

Output:

ChronoLocalDate before adjustment: 2018-12-06
ChronoLocalDate after adjustment: 2018-03-31
