Java ZoneOffsetTransitionRule getStandardOffset()用法及代码示例

java.time.zone.ZoneOffsetTransitionRule类的getStandardOffset()方法用于获取发生转换所依据的标准Zone偏移量的对象。

用法:

public ZoneOffset getStandardOffset()

参数：此方法不接受任何参数。

返回值：此方法返回发生过渡的标准区域偏移的对象。

下面是说明getStandardOffset()方法的示例：

范例1：

// Java program to demonstrate 
// getStandardOffset() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.zone.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing 
        // ZoneOffsetTransitionRule Object 
        ZoneOffsetTransitionRule zonetrans1 
            = ZoneOffsetTransitionRule 
                  .of( 
                      Month.JANUARY, 12, 
                      DayOfWeek.SUNDAY, 
                      LocalTime.of(03, 24, 45), 
                      false, 
                      ZoneOffsetTransitionRule 
                          .TimeDefinition 
                          .STANDARD, 
                      ZoneOffset.ofTotalSeconds(8), 
                      ZoneOffset.ofTotalSeconds(17), 
                      ZoneOffset.ofTotalSeconds(12)); 
  
        // getting object of Zone offset 
        // by using getStandardOffset() method 
        ZoneOffset off 
            = zonetrans1.getStandardOffset(); 
  
        // display the result 
        System.out.println( 
            "standard Zone Offset:" + off); 
    } 
}

输出：

standard Zone Offset:+00:00:08

范例2：

// Java program to demonstrate 
// getStandardOffset() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.zone.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
  
        // creating and initializing 
        // ZoneOffsetTransitionRule Object 
        ZoneOffsetTransitionRule zonetrans1 
            = ZoneOffsetTransitionRule 
                  .of( 
                      Month.JANUARY, 12, 
                      DayOfWeek.SUNDAY, 
                      LocalTime.of(03, 24, 45), 
                      false, 
                      ZoneOffsetTransitionRule 
                          .TimeDefinition 
                          .STANDARD, 
                      ZoneOffset.ofTotalSeconds(21), 
                      ZoneOffset.ofTotalSeconds(17), 
                      ZoneOffset.ofTotalSeconds(12)); 
  
        // getting object of Zone offset 
        // by using getStandardOffset() method 
        ZoneOffset off 
            = zonetrans1.getStandardOffset(); 
  
        // display the result 
        System.out.println( 
            "standard Zone Offset:" + off); 
    } 
}

输出：

standard Zone Offset:+00:00:21
