The minusYears() method of a ZonedDateTime class used to subtract the number of years from this ZonedDateTime and return a copy of ZonedDateTime after subtraction.This method operates on the local time-line, subtract years from the local date-time and after subtracting years 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 minusYears(long years)
Parameters: This method accepts a single parameter years which represents the years to subtract, It can be negative.
Return value: This method returns a ZonedDateTime based on this date-time with the years subtracted.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the minusYears() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.minusYears() 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" + " subtracting years: " + zoneddatetime); // subtract 15 years ZonedDateTime returnvalue = zoneddatetime.minusYears(5); // print result System.out.println("ZonedDateTime after " + "subtracting 15 years: " + returnvalue); }} |
ZonedDateTime before subtracting years: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after subtracting 15 years: 2013-12-06T19:21:12.123+05:30[Asia/Calcutta]
Program 2:
// Java program to demonstrate// ZonedDateTime.minusYears() 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" + " subtracting years: " + zoneddatetime); // subtract 12 years ZonedDateTime returnvalue = zoneddatetime.minusYears(12); // print result System.out.println("ZonedDateTime after " + "subtracting 12 years: " + returnvalue); }} |
ZonedDateTime before subtracting years: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after subtracting 12 years: 2006-10-25T23:12:31.123+02:00[Europe/Paris]
