Instant from() method in Java with Examples
The from() method of Instant class helps to get instance of instant from TemporalAccessor object passed as parameter. A TemporalAccessor represents an arbitrary set of date and time information and this method helps to get an instant based on the specified TemporalAccessor object. The conversion of TemporalAccessor object to instant extracts the INSTANT_SECONDS and NANO_OF_SECOND fields. Syntax:
public static Instant
from(TemporalAccessor temporal)
Parameters: This method accepts only one parameter temporal which represents the temporal object. It should not be null. Returns: This method returns Instant object from the TemporalAccessor Object. It should not be null. Exception: This method throws DateTimeException if method is unable to convert temporal object to an Instant. Below programs illustrate the from() method: Program 1:
Java
import java.time.*;
public class GFG {
public static void main(String[] args)
{
ZonedDateTime zonedDateTime
= ZonedDateTime.now();
System.out.println("ZonedDateTime: "
+ zonedDateTime);
Instant result = Instant.from(zonedDateTime);
System.out.println("Instant: "
+ result);
}
}
|
Output:
ZonedDateTime: 2018-11-27T04:58:47.691Z[Etc/UTC]
Instant: 2018-11-27T04:58:47.691Z
Program 2:
Java
import java.time.*;
public class GFG {
public static void main(String[] args)
{
OffsetDateTime offset
= OffsetDateTime.now();
System.out.println("OffsetDateTime: "
+ offset);
Instant result = Instant.from(offset);
System.out.println("Instant: "
+ result);
}
}
|
Output:
OffsetDateTime: 2018-11-27T04:58:50.588Z
Instant: 2018-11-27T04:58:50.588Z
