    public void setEndRule(int en_mm, int en_dd, int en_time);
public void setEndRule(int en_mm, int en_dd, int en_dow, int en_time);
public void setEndRule(int en_mm, int en_dd,int en_dow, int en_time, boolean status);

• setEndRule() method is available in java.util package.

  setEndRule()方法在java.util包中可用。

• setEndRule(int en_mm, int en_dd, int en_time) method is used to set the ending rule of DST(Daylight Savings Time) to the given fixed date (dd) in a month.

  setEndRule(int en_mm，int en_dd，int en_time)方法用于将DST(夏令时)的结束规则设置为一个月中的给定固定日期(dd)。

• setEndRule(int en_mm, int en_dd,int en_dow, int en_time) method is used to set the end rule of DST(Daylight Savings Time).

  setEndRule(int en_mm，int en_dd，int en_dow，int en_time)方法用于设置DST(夏令时)的结束规则。

• setEndRule(int en_mm, int en_dd, int en_dow, int en_time, boolean status) method is used to set the ending rule of DST(Daylight Savings Time) to the earlier weekday (dow) or after the given date (dd) in a month.

  setEndRule(int en_mm，int en_dd，int en_dow，int en_time，布尔状态)方法用于将DST(夏令时)的结束规则设置为较早的工作日(dow)或一个月中给定日期(dd)之后。

• These methods may throw an exception at the time of setting end rule.

Example:

例：

// Java program to demonstrate the example 
// of setEndRule() method of SimpleTimeZone
import java.util.*;
public class SetEndRuleOfSimpleTimeZone {
public static void main(String args[]) {
// Instantiates SimpleTimeZone object
SimpleTimeZone s_tz1 = new SimpleTimeZone(360, "FRANCE");
SimpleTimeZone s_tz2 = new SimpleTimeZone(760, "JAPAN");
SimpleTimeZone s_tz3 = new SimpleTimeZone(39800000, "US",
Calendar.APRIL, 6, -Calendar.MONDAY, 7200000, Calendar.OCTOBER, -1,
Calendar.MONDAY, 7200000, 3600000);
// By using setEndRule() method is used to
// set the DST end rule to a constant date
s_tz1.setEndRule(Calendar.JUNE, Calendar.MONDAY, 3800000);
// By using setEndRule() method is used to
// set the DST end rule to a weekday before
// or after the given date
s_tz2.setEndRule(Calendar.JUNE, Calendar.MONDAY, 2, 3800000, false);
// By using setEndRule() method is used to
// set the DST end rule 
s_tz3.setEndRule(Calendar.JUNE, Calendar.MONDAY, 2, 3800000);
// Display SimpleTimeZone
System.out.print("s_tz1.setEndRule(Calendar.JUNE, Calendar.MONDAY,3800000): ");
System.out.println(s_tz1);
System.out.print("s_tz2.setEndRule(Calendar.JUNE, Calendar.MONDAY,3800000,false): ");
System.out.println(s_tz1);
System.out.print("s_tz3.setEndRule(Calendar.JUNE, Calendar.MONDAY,2,3800000): ");
System.out.println(s_tz1);
}
}
