The adjustInto() method of ChronoLocalDate interface in Java is used to adjusts the specified temporal object to have the same date as this object.
Syntax:
public Temporal adjustInto(Temporal temporal)
Parameter: This method accepts a single parameter temporal which is the target object to be adjusted, and not specifically null.
Return Value: It returns the adjusted object, not null.
Exceptions: The function throws two exceptions as described below:
- DateTimeException: the program throws this if it is unable to make the adjustment.
- ArithmeticException: the program throws this if there is a numeric overflow.
Below programs illustrate the adjustInto() method of ChronoLocalDate in Java:
Program 1:
// Program to illustrate the adjustInto() method import java.util.*;
import java.time.*;
import java.time.chrono.*;
public class GfG {
public static void main(String[] args)
{
ZonedDateTime date
= ZonedDateTime.now();
// prints the date
System.out.println(date);
// Parses the date
ChronoLocalDate date1
= LocalDate.parse( "2015-01-31" );
// Uses the function to adjust the date
date = (ZonedDateTime)date1.adjustInto(date);
// Prints the adjusted date
System.out.println(date);
}

Program 2: To illustrate Exception. The below program throws an exception as February is of 28 days and not 31 days.
// Program to illustrate the adjustInto() method // Exception Program import java.util.*;
import java.time.*;
import java.time.chrono.*;
public class GfG {
public static void main(String[] args)
{
try {
ZonedDateTime date
= ZonedDateTime.now();
// prints the date
System.out.println(date);
// Parses the date
ChronoLocalDate date1
= LocalDate.parse( "2015-02-31" );
// Uses the function to adjust the date
date = (ZonedDateTime)date1.adjustInto(date);
// Prints the adjusted date
System.out.println(date);
}
catch (Exception e) {
System.out.println(e);
}
}
