The adjustInto() method of LocalDate class 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:
  1. DateTimeException: the program throws this if it is unable to make the adjustment.
  2. ArithmeticException: the program throws this if there is a numeric overflow.
Below programs illustrate the adjustInto() method of LocalDate in Java: Program 1:
// Program to illustrate the adjustInto() method
  
import java.util.*;
import java.time.*;
  
public class GfG {
    public static void main(String[] args)
    {
  
        ZonedDateTime date = ZonedDateTime.now();
  
        // prints the date
        System.out.println(date);
  
        // Parses the date
        LocalDate 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);
    }
}

                    
Output:
2018-11-28T05:36:08.205Z[Etc/UTC]
2015-01-31T05:36:08.205Z[Etc/UTC]
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.*;
  
public class GfG {
    public static void main(String[] args)
    {
        try {
            ZonedDateTime date = ZonedDateTime.now();
  
            // prints the date
            System.out.println(date);
  
            // Parses the date
            LocalDate 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);
        }
    }
}

                    
Output:
2018-11-28T05:36:11.014Z[Etc/UTC]
java.time.format.DateTimeParseException: 
Text '2015-02-31' could not be parsed: Invalid date 'FEBRUARY 31'
