The adjustInto() method of OffsetDateTime class in Java adjusts the specified temporal object to have the same date and time as this object.
Syntax :
public Temporal adjustInto(Temporal temporal)
Parameter : This method accepts a single parameter temporal which specifies the target object to be adjusted, not null.
Return Value: It returns the adjusted object, not null
Errors and exception : This method throws two exceptions as described below:
- DateTimeException: if unable to make the adjustment.
- ArithmeticException: if numeric overflow occurs.
Below programs illustrate the adjustInto() method:
Program 1 :
// Java program to demonstrate the adjustInto() method  import java.time.OffsetDateTime;import java.time.ZonedDateTime;  public class GFG {    public static void main(String[] args)    {          // Current time        ZonedDateTime date = ZonedDateTime.now();          // Prints the current date        System.out.println("Current date is: " + date);          // Parses the date        OffsetDateTime date1 = OffsetDateTime.parse("2018-12-12T13:30:30+05:00");          // Function used        date = (ZonedDateTime)date1.adjustInto(date);          // Prints the date        System.out.println(date);    }} |
Output:
Current date is: 2018-12-11T09:53:15.294Z[Etc/UTC] 2018-12-12T13:30:30Z[Etc/UTC]
Program 2 :
// Java program to demonstrate the adjustInto() method// exceptions  import java.time.OffsetDateTime;import java.time.ZonedDateTime;  public class GFG {    public static void main(String[] args)    {        try {            // Current time            ZonedDateTime date = ZonedDateTime.now();              // Prints the current date            System.out.println("Current date is: " + date);              // Parses the date            OffsetDateTime date1 = OffsetDateTime.parse("2018-13-12T13:30:30+05:00");              // Function used            date = (ZonedDateTime)date1.adjustInto(date);              // Prints the date            System.out.println(date);        }        catch (Exception e) {            System.out.println(e);        }    }} |
Output:
Current date is: 2018-12-11T09:53:24.660Z[Etc/UTC] java.time.format.DateTimeParseException: Text '2018-13-12T13:30:30+05:00' could not be parsed: Invalid value for MonthOfYear (valid values 1 - 12): 13
