Java中的 SimpleTimeZone setEndRule(int, int, int) 方法及示例

Java中 SimpleTimeZone 类的 setEndRule(int endofMonth , int endofDay , int endofTime ) 方法用于将夏令时的特定规则设置为给定月份内的固定日期。

句法：

public void setEndRule(int endofMonth, 
                            int endofDay, 
                            int endofTime)

参数：该方法接受三个参数：

• endofMonth ：这是 Integer 类型，指的是夏令时的结束月份。
• endofDay ：这是整数类型，指的是夏令时的结束日期。
• endofTime ：Integer 类型，指夏令时的结束时间。

返回值：该方法不返回任何值。

下面的程序说明了在Java中使用 setEndRule() 方法：
示例 1：

// Java code to demonstrate
// setEndRule() method
  
import java.util.*;
  
public class SimpleTimeZone_Demo {
    public static void main(String[] args)
    {
  
        // Creating SimpleTimeZone object
        SimpleTimeZone simtimeobj
            = new SimpleTimeZone(100, "GMT");
  
        // Displaying the Initial value
        System.out.println(
            "Initial value: " + simtimeobj);
  
        // Setting an EnDRule
        simtimeobj.setEndRule(Calendar.APRIL,
                              28, 3600000);
  
        // Displaying the New value
        System.out.println(
            "New value: " + simtimeobj);
    }
}

输出：

Initial value: java.util.SimpleTimeZone[id=GMT, offset=100, 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]

New value: java.util.SimpleTimeZone[id=GMT, offset=100, dstSavings=3600000,
useDaylight=false, startYear=0, startMode=0, startMonth=0, startDay=0, startDayOfWeek=0,
startTime=0, startTimeMode=0, endMode=1, endMonth=3, endDay=28, endDayOfWeek=0,
endTime=3600000, endTimeMode=0]

示例 2：

// Java code to demonstrate
// setEndRule() method
  
import java.util.*;
  
public class SimpleTimeZone_Demo {
    public static void main(String[] args)
    {
  
        // Creating SimpleTimeZone object
        SimpleTimeZone simtimeobj
            = new SimpleTimeZone(120, "GMT");
  
        // Displaying the Initial value
        System.out.println(
            "Initial value: " + simtimeobj);
  
        // Setting an EnDRule
        simtimeobj.setEndRule(Calendar.JANUARY,
                              15, 3600000);
  
        // Displaying the New value
        System.out.println(
            "New value: " + simtimeobj);
    }
}

输出：

Initial value: java.util.SimpleTimeZone[id=GMT, offset=120, 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]

New value: java.util.SimpleTimeZone[id=GMT, offset=120, dstSavings=3600000,
useDaylight=false, startYear=0, startMode=0, startMonth=0, startDay=0, startDayOfWeek=0,
startTime=0, startTimeMode=0, endMode=1, endMonth=0, endDay=15, endDayOfWeek=0,
endTime=3600000, endTimeMode=0]
