描述 (Description)
setStartRule(int startMonth, int startDay, int startDayOfWeek, int startTime)方法用于设置夏令时开始规则。
声明 (Declaration)
以下是java.util.SimpleTimeZone.setStartRule()方法的声明。
public void setStartRule(int startMonth,
int startDay,
int startDayOfWeek,
int startTime)
参数 (Parameters)
startMonth - 开始月份的夏令时。
startDay - 夏令时开始的月份中的某一天。
startDayOfWeek - 从星期几开始的夏令时。
startTime - 本地挂钟时间的夏令时开始时间。
返回值 (Return Value)
NA
异常 (Exception)
IllegalArgumentException - 如果startMonth，startDay，startDayOfWeek或startTime参数超出范围，则抛出此异常。
例子 (Example)
以下示例显示了java.util.SimpleTimeZone.setStartRule（）的用法
package com.iowiki;
import java.util.*;
public class SimpleTimeZoneDemo {
public static void main( String args[] ) {
// create simple time zone object
SimpleTimeZone stobj = new SimpleTimeZone(820,"GMT");
// checking initial value
System.out.println("Initial value: " + stobj);
// setting start rule
stobj.setStartRule( Calendar.MAY, 2,2, 3600000);
// checking the new value
System.out.println("Final value : " + stobj);
}
}
让我们编译并运行上面的程序，这将产生以下结果。
Initial value: java.util.SimpleTimeZone[id = GMT,offset = 820,dstSavings = 3600000,
useDaylight = false,startYear = 0,startMode = 0,startMonth = 0,startDay = 0,
startDayOfWeek = 0,startTime = 0,startTimeMode = 0,endMode = 0,endMonth = 0,
endDay = 0,endDayOfWeek = 0,endTime = 0,endTimeMode = 0]
Final value : java.util.SimpleTimeZone[id = GMT,offset = 820,
dstSavings = 3600000,useDaylight = false,startYear = 0,startMode = 2,
startMonth = 4,startDay = 2,startDayOfWeek = 2,startTime = 3600000,
startTimeMode = 0,endMode = 0,endMonth = 0,endDay = 0,endDayOfWeek = 0,
endTime = 0,endTimeMode = 0]
