SimpleTimeZone setEndRule(int, int, int) in Java

setEndRule(int, int, int): This method is available in java.util.SimpleTimeZone class of Java.

Syntax:

void java.util.SimpleTimeZone.setEndRule(int endMonth, int endDay, int endTime)

This method takes three arguments. This method sets the daylight saving time end rule to a fixed date within a month.

Parameters: Three parameters are required for this method.

endMonth: The daylight saving time ending month.

endDay: The day of the month on which the daylight saving time ends.

endTime: The daylight saving ending time in local wall clock time,(in milliseconds within the day) which is local daylight time in this case.

Throws:

IllegalArgumentException - the endMonth, endDay, or endTime parameters are out of range.

Approach 1: When no exception

Java

import java.util.SimpleTimeZone;

public class SimpleTimeZonesetEndRule {
    public static void main(String[] args) {

        SimpleTimeZone simpleTimeZone = 
                      new SimpleTimeZone(100, "India");

        int endMonth = 5, endDay = 12, endTime = 18;
        simpleTimeZone.setEndRule(endMonth, endDay, endTime);
        System.out.println(simpleTimeZone);
    }
}

Output:

java.util.SimpleTimeZone[id=India,offset=100,dstSavings=3600000,useDaylight=false,startYear=0,startMode=0,startMonth=0,startDay=0,startDayOfWeek=0,startTime=0,startTimeMode=0,endMode=1,endMonth=5,endDay=12,endDayOfWeek=0,endTime=18,endTimeMode=0]

Approach 2: IllegalArgumentException

Java

import java.util.SimpleTimeZone;

public class SimpleTimeZonesetEndRule {
    public static void main(String[] args) {

        SimpleTimeZone simpleTimeZone = 
                  new SimpleTimeZone(100, "India");

        int endMonth = 13, endDay = 12, endTime = 18;
        simpleTimeZone.setEndRule(endMonth, endDay, endTime);
        System.out.println(simpleTimeZone);
    }
}

Output:

Exception in thread "main" java.lang.IllegalArgumentException: Illegal end month 13
