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);
}
