Java 中的 ZoneOffsetTransitionRule createTransition()方法，示例

原文:https://www . geeksforgeeks . org/zoneoffsettransitionrule-create transition-method-in-Java-with-example/

Java . time . zoneoffset transitionrule类的 createTransition() 方法用于 创建特定年份的特定区域偏移转换的对象。

语法:

public ZoneOffsetTransition createTransition(int year)

参数:该方法取必须生成过渡实例的整数值年份..

返回值:该方法返回特定年份特定区域偏移过渡的对象。

以下是说明 createTransition() 方法的示例:

例 1:

// Java program to demonstrate
// createTransition() 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(10),
                      ZoneOffset.ofTotalSeconds(12));

        // getting object of ZoneOffsetTransition
        // by using createTransition() method
        ZoneOffsetTransition zoo
            = zonetrans1.createTransition(10);

        // display the result
        System.out.println("ZoneOffsetTransition : "
                           + zoo);
    }
}

Output:

区域偏移转换:转换[0010-01-17T 03:24:47+00:00:10 到+00:00:12 的间隙]

例 2:

// Java program to demonstrate
// createTransition() 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(10),
                      ZoneOffset.ofTotalSeconds(12));

        // getting object of ZoneOffsetTransition
        // by using createTransition() method
        ZoneOffsetTransition zoo
            = zonetrans1.createTransition(14);

        // display the result
        System.out.println(
            "ZoneOffsetTransition : "
            + zoo);
    }
}

Output:

区域偏移转换:转换[0014-01-12t 03:24:47+00:00:10 到+00:00:12 的间隙]
