ZonedDateTime plusWeeks() method in Java with Examples Last Updated : 10 Dec, 2018 Comments Improve Suggest changes Like Article Like Report plusWeeks() method of a ZonedDateTime class used to add the number of weeks in this ZonedDateTime and return a copy of ZonedDateTime after addition.This method operates on the local time-line, adds weeks to the local date-time and after adding weeks local date-time is converted back to a ZonedDateTime, using the zone ID to obtain the offset. When converting back to ZonedDateTime, if the local date-time is in an overlap, then the offset will be retained if possible, otherwise, the earlier offset will be used. This instance is immutable and unaffected by this method call. Syntax: public ZonedDateTime plusWeeks(long weeks) Parameters: This method accepts a single parameter weeks which represents the weeks to add, It can be negative. Return value: This method returns a ZonedDateTime based on this date-time with the weeks added. Exception: This method throws DateTimeException if the result exceeds the supported date range. Below programs illustrate the plusWeeks() method: Program 1: Java // Java program to demonstrate // ZonedDateTime.plusWeeks() 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 weeks: " + zoneddatetime); // add 10 weeks ZonedDateTime returnvalue = zoneddatetime.plusWeeks(10); // print result System.out.println("ZonedDateTime after " + "adding 10 weeks: " + returnvalue); } } Output: ZonedDateTime before adding weeks: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] ZonedDateTime after adding 10 weeks: 2019-02-14T19:21:12.123+05:30[Asia/Calcutta] Program 2: Java // Java program to demonstrate // ZonedDateTime.plusWeeks() 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 weeks: " + zoneddatetime); // add 2 weeks ZonedDateTime returnvalue = zoneddatetime.plusWeeks(2); // print result System.out.println("ZonedDateTime after " + "adding 2 weeks: " + returnvalue); } } Output: ZonedDateTime before adding weeks: 2018-10-25T23:12:31.123+02:00[Europe/Paris] ZonedDateTime after adding 2 weeks: 2018-11-08T23:12:31.123+01:00[Europe/Paris] Reference: https://docs.oracle.com/javase/10/docs/api/java/time/ZonedDateTime.html#plusWeeks(long) Comment More infoAdvertise with us Next Article ZonedDateTime plusWeeks() method in Java with Examples A AmanSingh2210 Follow Improve Article Tags : Java Java-Functions Java-time package Java-ZonedDateTime Practice Tags : Java Similar Reads ZonedDateTime minusWeeks() method in Java with Examples minusWeeks() method of a ZonedDateTime class used to subtract the number of weeks from this ZonedDateTime and return a copy of ZonedDateTime after subtraction.This method operates on the local time-line, subtracts weeks to the local date-time and after subtracting weeks local date-time is converted 2 min read ZonedDateTime plus() method in Java with Examples In ZonedDateTime class, there are two types of plus() method depending upon the parameters passed to it. plus(long amountToAdd, TemporalUnit unit) plus() method of a ZonedDateTime class used to return a copy of this date-time with the specified amount of unit added.If it is not possible to add the a 2 min read ZonedDateTime plusYears() method in Java with Examples The plusYears() method of a ZonedDateTime class used to add the number of years in this ZonedDateTime and return a copy of ZonedDateTime after addition.This method operates on the local time-line, adds years to the local date-time and after adding years local date-time is converted back to a ZonedDa 2 min read ZonedDateTime plusDays() method in Java with Examples The plusDays() method of ZonedDateTime class in Java is used to add the number of specified days in this ZonedDateTime instance and return a copy of ZonedDateTime.
