minusMonths() method of a ZonedDateTime class used to subtracts the number of months in this ZonedDateTime and return a copy of ZonedDateTime after subtraction. This instance is immutable and unaffected by this method call.
Syntax:
public ZonedDateTime minusMonths(long months)
Parameters: This method accepts a single parameter months which represents the months to subtract, It can be negative.
Return value: This method returns a ZonedDateTime based on this date-time with the months subtract, not null.
Exception: This method throws DateTimeException if the result exceeds the supported date range.
Below programs illustrate the minusMonths() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.minusMonths() 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 months: " + zoneddatetime); // subtract 10 months ZonedDateTime returnvalue = zoneddatetime.minusMonths(10); // print result System.out.println("ZonedDateTime after " + " subtracting 10 months: " + returnvalue); }} |
ZonedDateTime before subtracting months: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
ZonedDateTime after subtracting 10 months: 2018-02-06T19:21:12.123+05:30[Asia/Calcutta]
Program 2:
// Java program to demonstrate// ZonedDateTime.minusMonths() 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 months: " + zoneddatetime); // subtract 2 months ZonedDateTime returnvalue = zoneddatetime.minusMonths(2); // print result System.out.println("ZonedDateTime after " + " subtracting 2 months: " + returnvalue); }} |
ZonedDateTime before subtracting months: 2018-10-25T23:12:31.123+02:00[Europe/Paris]
ZonedDateTime after subtracting 2 months: 2018-08-25T23:12:31.123+02:00[Europe/Paris]
