SimpleTimeZone类setEndRule()方法 (SimpleTimeZone Class setEndRule() method)

Syntax:

句法&＃xff1a;

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&＃xff0c;int en_dd&＃xff0c;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&＃xff0c;int en_dd&＃xff0c;int en_dow&＃xff0c;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&＃xff0c;int en_dd&＃xff0c;int en_dow&＃xff0c;int en_time&＃xff0c;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.

  这些方法在设置结束规则时可能会引发异常。

  IllegalArgumentException: This exception may throw when any one of the parameters is not in a range.

  IllegalArgumentException &＃xff1a;当任何一个参数不在范围内时&＃xff0c;可能引发此异常。

• These are non-static methods and it is accessible with the class object only and if we try to access these methods with the class name then we will get an error.

  这些是非静态方法&＃xff0c;只能通过类对象访问&＃xff0c;如果尝试使用类名称访问这些方法&＃xff0c;则会收到错误消息。

Parameter(s):

参数&＃xff1a;

• In the first case, setEndRule(int en_mm, int en_dd,int en_time)

  在第一种情况下&＃xff0c; setEndRule(int en_mm&＃xff0c;int en_dd&＃xff0c;int en_time)

  • int en_mm – represents the DST ending month.
  • int en_mm –表示夏令时结束的月份。
  • int en_dd – represents the DST ending day of month.
  • int en_dd –表示夏令时结束的月份。
  • int en_time – represents the DST ending time.
  • int en_time –表示DST的结束时间。

• In the second case, setEndRule(int en_mm, int en_dd,int en_dow,int en_time),

  在第二种情况下&＃xff0c; setEndRule(int en_mm&＃xff0c;int en_dd&＃xff0c;int en_dow&＃xff0c;int en_time) &＃xff0c;

  • int en_mm – represents the DST ending month.
  • int en_mm –表示夏令时结束的月份。
  • int en_dd – represents the DST ending day of month.
  • int en_dd –表示夏令时结束的月份。
  • int en_dow – represents DST last day of week.
  • int en_dow –表示夏令时。
  • int en_time – represents the DST ending time.
  • int en_time –表示DST的结束时间。

• In the second case, setEndRule(int en_mm, int en_dd,int en_dow,int en_time,boolean status),

  在第二种情况下&＃xff0c; setEndRule(int en_mm&＃xff0c;int en_dd&＃xff0c;int en_dow&＃xff0c;int en_time&＃xff0c;布尔值状态) &＃xff0c;

  • int en_mm – represents the DST ending month.
  • int en_mm –表示夏令时结束的月份。
  • int en_dd – represents the DST ending day of month.
  • int en_dd –表示夏令时结束的月份。
  • int en_dow – represents DST last day of week.
  • int en_dow –表示夏令时。
  • int en_time – represents the DST ending time.
  • int en_time –表示DST的结束时间。
  • boolean status – sets to true then this rule selects first en_dow on or after en_dd otherwise this rule selects last en_dow on or before en_dd.
  • 布尔状态 –设置为true&＃xff0c;然后此规则选择在en_dd或之后的第一个en_dow&＃xff0c;否则该规则选择在en_dd或之前的最后一个en_dow。

Return value:

返回值&＃xff1a;

In all cases, the return type of the method is void – It returns nothing.

在所有情况下&＃xff0c;该方法的返回类型均为空 –它不返回任何内容。

Example:

例&＃xff1a;

// 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 &＃61; new SimpleTimeZone(360, "FRANCE");
SimpleTimeZone s_tz2 &＃61; new SimpleTimeZone(760, "JAPAN");
SimpleTimeZone s_tz3 &＃61; 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);
}
}
