Instant adjustInto() method in Java with Example
The adjustInto(Temporal temporal) method of Instant class adjusts the passed temporal object to have this instant on which this method is applied.
Syntax:
public Temporal adjustInto(Temporal temporal)
Parameters: This method accepts a parameter temporal which is the target temporal object to be adjusted. It should not be null.
Return Value: This method returns the adjusted temporal object.
Exception: This method throws following exceptions:
- DateTimeException if this method is unable to make the adjustment.
- ArithmeticException if numeric overflow occurs while adjusting.
Below programs illustrate the Instant.adjustInto() method:
Program 1:
// Java program to demonstrate// Instant.adjustInto() method  import java.time.*;import java.time.temporal.Temporal;  public class GFG {      public static void main(String[] args)    {          // create an instance object        Instant instant            = Instant.parse("2018-11-20T16:55:30.00Z");          // create a Temporal object        // which is equal to OffsetDateTime object        OffsetDateTime passTemporal            = OffsetDateTime.now();          // print passed Value        System.out.println("Passed Value: "                           + passTemporal);          // apply adjustInto method        // to adjust OffsetDateTime Temporal        // to instant object        Temporal returnTemporal            = instant.adjustInto(passTemporal);          // print results        System.out.println("Returned Value: "                           + (OffsetDateTime)returnTemporal);    }} |
Output:
Passed Value: 2018-11-22T09:22:17.297Z Returned Value: 2018-11-20T16:55:30Z
Program 2:
// Java program to demonstrate// Instant.adjustInto() method  import java.time.*;import java.time.temporal.Temporal;  public class GFG {    public static void main(String[] args)    {          // create an instance object        Instant instant            = Instant.parse("2018-11-17T06:50:39.00Z");          // create a Temporal object        // which is equal to ZonedDateTime object        ZonedDateTime passTemporal            = ZonedDateTime.now();          // print passed Value        System.out.println("Passed Value: "                           + passTemporal);          // apply adjustInto method        // to adjust ZonedDateTime Temporal        // to instant object        Temporal returnTemporal            = instant.adjustInto(passTemporal);          // print results        System.out.println("Returned Value: "                           + (ZonedDateTime)returnTemporal);    }} |
Output:
Passed Value: 2018-11-22T09:22:20.995Z[Etc/UTC] Returned Value: 2018-11-17T06:50:39Z[Etc/UTC]
Program 3:
// Java program to demonstrate// Instant.adjustInto() method  import java.time.*;import java.time.temporal.Temporal;  public class GFG {    public static void main(String[] args)    {          // create an instance object        Instant instant            = Instant.parse("2017-11-01T16:25:00.00Z");          // create a Temporal object        // which is equal to Instant object        // with current Instant        Temporal passTemporal            = Instant.now();          // print passed Value        System.out.println("Passed Value: "                           + passTemporal);          // apply adjustInto method to adjust Temporal        // to this instant object        Temporal returnTemporal            = instant.adjustInto(passTemporal);          // print results        System.out.println("Returned Value: "                           + returnTemporal);    }} |
Output:
Passed Value: 2018-11-22T09:22:23.298Z Returned Value: 2017-11-01T16:25:00Z
