SimpleTimeZone setEndRule(int, int, int, int) in Java

setEndRule(int, 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 endDayOfWeek, int endTime)

This method takes four arguments. This method sets the daylight saving time end rule.

Parameters: Four 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.

endDayOfWeek: The daylight saving time ending day-of-week.

endTime: The daylight saving ending time in the local wall clock time.

Throws:

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

Approach 1: When no exception

Java

import java.util.SimpleTimeZone;

public class SimpleTimeZonesetEndRule2 {
    public static void main(String[] args) {

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

        int endMonth = 5, endDay = 2, 
                        endDayOfWeek = 2, endTime = 18;

        simpleTimeZone.setEndRule(endMonth, 
                           endDay, endDayOfWeek, 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=2,endMonth=5,endDay=2,endDayOfWeek=2,endTime=18,endTimeMode=0]

Approach 2: IllegalArgumentException 

Java

import java.util.SimpleTimeZone;

public class SimpleTimeZonesetEndRule2 {
    public static void main(String[] args) {

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

        int endMonth = 15, endDay = 2, 
                   endDayOfWeek = 2, endTime = 18;

        simpleTimeZone.setEndRule(endMonth,
                       endDay, endDayOfWeek, endTime);

        System.out.println(simpleTimeZone);
    }
}

Output:

Exception in thread "main" java.lang.IllegalArgumentException: Illegal end month 15
