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
