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
