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);    }} |
Output:
2019-04-28T19:58:13.775Z[Etc/UTC] 2015-01-31T19:58:13.775Z[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.*;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);        }    }} |
Output:
2019-04-28T19:58:17.219Z[Etc/UTC] java.time.format.DateTimeParseException: Text '2015-02-31' could not be parsed: Invalid date 'FEBRUARY 31'
