Java 中的 SimpleTimeZone setStartYear()方法
原文:https://www . geesforgeks . org/simple time zone-setstartyear-method-in-Java/
简单时区类的设置开始年份()方法用于设置夏令时开始年份。
语法:
public void setStartYear(int year)
参数:该功能接受单个参数年份，指定夏令时开始年份。
返回值:该方法没有返回值。
异常:函数不抛出任何异常。
下面的程序演示了上述功能:
程序 1:
// program to demonstrate the
// function SimpleTimeZone.setStartYear()
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// create simple time zone object
SimpleTimeZone obj
= new SimpleTimeZone(500, "US");
// printing
System.out.println("SimpleTimeZone: "
+ obj);
// setting start year
obj.setStartYear(2000);
System.out.println("\nStartYear "
+ "set to 2000\n");
// printing the final value
System.out.println("SimpleTimeZone: "
+ obj);
}
}
Output:
SimpleTimeZone: java.util.SimpleTimeZone[
id=US,
offset=500,
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]
StartYear set to 2000
SimpleTimeZone: java.util.SimpleTimeZone[
id=US,
offset=500,
dstSavings=3600000,
useDaylight=false,
startYear=2000,
startMode=0,
startMonth=0,
startDay=0,
startDayOfWeek=0,
startTime=0,
startTimeMode=0,
endMode=0,
endMonth=0,
endDay=0,
endDayOfWeek=0,
endTime=0,
endTimeMode=0]
程序 2:
// program to demonstrate the
// function SimpleTimeZone.setStartYear()
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// create simple time zone object
SimpleTimeZone obj
= new SimpleTimeZone(620, "US");
// printing
System.out.println("SimpleTimeZone: "
+ obj);
// setting start year
obj.setStartYear(2018);
System.out.println("\nStartYear "
+ "set to 2018\n");
// printing the final value
System.out.println("SimpleTimeZone: "
+ obj);
}
}
Output:
SimpleTimeZone: java.util.SimpleTimeZone[
id=US,
offset=620,
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]
StartYear set to 2018
SimpleTimeZone: java.util.SimpleTimeZone[
id=US,
offset=620,
dstSavings=3600000,
useDaylight=false,
startYear=2018,
startMode=0,
startMonth=0,
startDay=0,
startDayOfWeek=0,
startTime=0,
startTimeMode=0,
endMode=0,
endMonth=0,
endDay=0,
endDayOfWeek=0,
endTime=0,
endTimeMode=0]
