Instant toString() method in Java with Examples

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.

// 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());
    }
}

// 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");
