The toString() method of Instant class returns string representation of this instant using ISO-8601 representation and format used is the same as DateTimeFormatter.ISO_INSTANT.
Syntax:
public String toString()
Returns: This method returns an ISO-8601 representation of this instant, not null.
Below programs illustrate the toString() method:
Program 1:
// Java program to demonstrate// Instant.toString() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a Instant object        Instant instant            = Instant.parse("2018-10-28T19:34:50.63Z");          // print Instant using toString()        System.out.println("Instant: "                           + instant.toString());          // addition of 84000 seconds to this instant        Instant returnedValue            = instant.plusSeconds(84000);          // print result Instant using toString()        System.out.println("Returned Instant: "                           + returnedValue.toString());    }} |
Program 2:
// Java program to demonstrate// Instant.toString() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a Instant object        Instant instant            = Instant.parse("2022-06-21T19:34:50.63Z");          // print Instant using toString()        System.out.println("Instant: "                           + instant);    }} |
