Java SimpleTimeZone setStartYear()方法

SimpleTimeZone类 的 setStartYear() 方法用于设置日光节约时间的起始年份。

语法

public void setStartYear(int year)

参数： 该函数接受一个单一的参数 year ，指定夏令时的起始年份。

返回值： 该方法没有返回值。

异常： 该函数没有抛出任何异常。

下面的程序演示了上述函数。

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);    }}

输出:

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 2000SimpleTimeZone: 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);    }}

输出:

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 2018SimpleTimeZone: 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]
