plusSeconds() method of a ZonedDateTime class used to add the number of seconds in this ZonedDateTime and return a copy of ZonedDateTime after addition.This method works on the instant time-line and adding one-second returns the time-line of one second later. Note that this method is a different approach to that used by days, months and years. This instance is immutable and unaffected by this method call.
Syntax:
public ZonedDateTime plusSeconds(long seconds)
Parameters: This method accepts a single parameter seconds which represents the seconds to add, It can be negative.
Return value: This method returns a ZonedDateTime based on this date-time with the seconds added.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the plusSeconds() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.plusSeconds() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zoneddatetime            = ZonedDateTime.parse(                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");          // print instance        System.out.println("ZonedDateTime before"                           + " adding seconds: "                           + zoneddatetime);          // add 3002 seconds        ZonedDateTime returnvalue            = zoneddatetime.plusSeconds(3002);          // print result        System.out.println("ZonedDateTime after "                           + " adding seconds: "                           + returnvalue);    }} |
ZonedDateTime before adding seconds: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after adding seconds: 2018-12-06T20:11:14.123+05:30[Asia/Calcutta]
Program 2:
// Java program to demonstrate// ZonedDateTime.plusSeconds() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zoneddatetime            = ZonedDateTime.parse(                "2018-10-25T23:12:31.123+02:00[Europe/Paris]");          // print instance        System.out.println("ZonedDateTime before"                           + " adding seconds: "                           + zoneddatetime);          // add 52 seconds        ZonedDateTime returnvalue            = zoneddatetime.plusSeconds(52);          // print result        System.out.println("ZonedDateTime after "                           + " adding seconds: "                           + returnvalue);    }} |
ZonedDateTime before adding seconds: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after adding seconds: 2018-10-25T23:13:23.123+02:00[Europe/Paris]
