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);     } } |
