Java SimpleTimeZone toString() Example
SimpleTimeZone class toString() method example. This example shows you how to use toString() method.
Syntax is : Public public String toString()
This method returns a string representation of this time zone.
Here is the code.
/**
* @(#) ToStringSimpleTimeZone.java
* A class representing use of method toString() of SimpleTimeZone
class in java.util Package.
* @Version 23-May-2008
* @author Rose India Team
*/
import java.util.*;
class ToStringSimpleTimeZone {
public static void main( String args[] ){
// Constructor of SimpleTimeZone class
SimpleTimeZone obj = new SimpleTimeZone(-28800000,
"America/Los_Angeles", Calendar.APRIL, 1,-Calendar.SUNDAY, 7200000,
Calendar.OCTOBER, -1, Calendar.SUNDAY, 7200000, 3600000);
System.out.println("Object obj has values : \n\n" + obj);
// toString() method call.
String str = obj.toString();
System.out.println("String representation of obj is :-\n\n" + str);
}
}
/* Note: Description of constructor of SimpleTimeZone class.
For example: // Base GMT offset: -8:00
// DST starts: at 2:00am in standard time
// on the first Sunday in April
// DST ends: at 2:00am in daylight time
// on the last Sunday in October
// Save: 1 hour
For these values constructor is:-
SimpleTimeZone(-28800000, "America/Los_Angeles", calendar.APRIL, 1,-Calendar.
SUNDAY, 7200000, Calendar.OCTOBER, -1, Calendar.SUNDAY, 7200000, 3600000)
There are some rules to pass the values of arguments in constructor:
# Exact day of month
To specify an exact day of month, set the month and day-of-month to an exact
value, and day-of-week to zero. For example, to specify March 1, set the
month to MARCH, day-of-month to 1, and day-of-week to 0.
# Day of week on or after day of month
To specify a day of week on or after an exact day of month, set the month to
an exact month value, day-of-month to the day on or after which the rule is
applied, and day-of-week to a negative DAY_OF_WEEK field value. For example,
to specify the second Sunday of April, set month to APRIL,day-of-month to 8,
and day-of-week to -SUNDAY.
# Day of week on or before day of month
To specify a day of the week on or before an exact day of the month, set
day-of-month and day-of-week to a negative value. For example, to specify
the last Wednesday on or before the 21st of March, set month to MARCH,
day-of-month is -21 and day-of-week is -WEDNESDAY.
# Last day-of-week of month
To specify, the last day-of-week of the month, set day-of-week to a
DAY_OF_WEEK value and day-of-month to -1. For example, to specify the last
Sunday of October, set month to OCTOBER, day-of-week to SUNDAY and
day-of-month to -1. */ |
Output of the program.
Object obj has values :
java.util.SimpleTimeZone[id=America/Los_Angeles,offset=-28800000,dstSavings=3600000,
useDaylight=true,startYear=0,startMode=3,startMonth=3,startDay=1,startDayOfWeek=1,
startTime=7200000,startTimeMode=0,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,
endTime=7200000,endTimeMode=0]
String representation of obj is :-
java.util.SimpleTimeZone[id=America/Los_Angeles,offset=-28800000,dstSavings=3600000,
useDaylight=true,startYear=0,startMode=3,startMonth=3,startDay=1,startDayOfWeek=1,
startTime=7200000,startTimeMode=0,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,
endTime=7200000,endTimeMode=0] |
