Java中的 ZoneOffsetTransition of() 方法示例

Java.time.zone.ZoneOffsetTransition类的of()方法用于借助本地日期时间、前偏移和后偏移创建区域偏移过渡的对象。

句法：

public static ZoneOffsetTransition of(LocalDateTime transition,
                                      ZoneOffset offsetBefore,
                                      ZoneOffset offsetAfter)

参数：此方法将以下参数作为参数。

• 过渡：必须为其创建过渡的本地日期时间对象。
• offsetBefore：初始过渡的区域偏移对象。
• offsetAfter：最终过渡的区域偏移对象。

返回值：该方法通过本地日期时间、前偏移和后偏移返回区域偏移过渡的对象。
以下是说明of()方法的示例：
示例 1：

Java

// Java program to demonstrate
// of() 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
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25,
                03, 24, 45, 0);
 
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(12);
 
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(8);
 
        // creating and initializing
        // ZoneOffsetTransition Object
        // by using of() method
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);
 
        // getting the string representation
        // of this object
        String str
            = zonetrans1.toString();
 
        // display the result
        System.out.println(
            "zone offset transition : "
            + str);
    }
}

输出：
区域偏移过渡：过渡[在 1999-04-25T03:24:45+00:00:12 到 +00:00:08 重叠]

示例 2：

Java

// Java program to demonstrate

import java.time.chrono.*;
import java.time.zone.*;
 
public class GFG {
    public static void main(String[] argv)
    {
 
        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                2018, 04, 25,
                03, 24, 45, 0);
 
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(12);
 
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(8);
 
        // creating and initializing
        // ZoneOffsetTransition Object
        // by using of() method
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);
 
        // getting the string representation
        // of this object
        String str = zonetrans1.toString();
 
        // display the result
        System.out.println(
            "zone offset transition : "
            + str);
    }
}

输出：
区域偏移过渡：过渡[在 2018-04-25T03:24:45+00:00:12 到 +00:00:08 重叠]
