Instant Class from() method

  • from() method is available in java.time package.
  • from() method is used to return a copy of the Instant from the given TemporalAccessor object.
  • from() method is a static method, it is accessible with the class name and if we try to access the method with the class object then we will not get an error.
  • from() method may throw an exception at the time of returning Instant from the given temp_acc.
    DateTimeException: This exception may throw when the given templ_acc couldn't convert into Instant.


    public static Instant from(TemporalAccessor temp_acc);


  • TemporalAccessor temp_acc – represents the temporal accessor to convert to Instant.

Return value:

The return type of this method is Instant, it returns the Instant that the holds the same value from the given object.


// Java program to demonstrate the example 
// of Instant from(TemporalAccessor temp_acc)
// method of Instant

import java.time.*;
public class FromOfInstant {
    public static void main(String args[]) {
        // Instantiates a OffsetDateTime 
        // and a ZonedDateTime object
        OffsetDateTime off_da_time =;
        ZonedDateTime zo_da_time = ZonedDateTime.parse("2008-07-06T20:25:30.213+03:00[Africa/Asmara]");

        // Display off_da_time
        // and zo_da_time
        System.out.println("OffsetDateTime off_da_time: ");
        System.out.println("off_da_time: " + off_da_time);
        System.out.println("ZonedDateTime zo_da_time: ");
        System.out.println("zo_da_time: " + zo_da_time);


        // Here, this method creates an Instant
        // from the given TemporalAccessor i.e.
        // here we are creating an Instant(ins)
        // from the given OffsetDateTime(off_da_time)
        Instant inst = Instant.from(off_da_time);

        // Display inst
        System.out.println("Instant.from(off_da_time): " + inst);

        // Here, this method creates an Instant
        // from the given TemporalAccessor i.e.
        // here we are creating an Instant(ins)
        // from the given ZonedDateTime(zo_da_time)
        inst = Instant.from(zo_da_time);

        // Display inst
        System.out.println("Instant.from(zo_da_time): " + inst);


OffsetDateTime off_da_time: 
off_da_time: 2020-05-21T22:00:46.891244Z

ZonedDateTime zo_da_time: 
zo_da_time: 2008-07-06T20:25:30.213+03:00[Africa/Asmara]

Instant.from(off_da_time): 2020-05-21T22:00:46.891244Z
Instant.from(zo_da_time): 2008-07-06T17:25:30.213Z
