Java 中的 ZoneOffsetTransition to pochssecond()方法,示例

原文:https://www . geeksforgeeks . org/zoneoffsettransition-toepochssecond-method-in-Java-with-example/

Java . time . zone . zoneoffset transition类的to pochssecond()方法用于获取该特定区域偏移转换对象的第二个纪元。

语法:

public long toEpochSecond()

参数:此方法不接受任何参数。

返回值:该方法返回该特定区域偏移过渡对象的历元秒。

以下是说明方法的示例:

例 1:

// Java program to demonstrate
// toEpochSecond() 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(8);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(12);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // getting the epoch second for this object
        // by using toEpochSecond() method
        long epocsec
            = zonetrans1.toEpochSecond();

        // display the result
        System.out.println(
            "epoch second : "
            + epocsec);
    }
}

输出:

epoch second : 925010677

例 2:

// Java program to demonstrate
// toEpochSecond() 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
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // getting the epoch second for this object
        // by using toEpochSecond() method
        long epocsec
            = zonetrans1.toEpochSecond();

        // display the result
        System.out.println("epoch second : "
                           + epocsec);
    }
}

输出:

epoch second : 925010673
