ZoneOffsetTransition getOffsetAfter()方法在 Java 中用示例

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

使用Java . time . zoneoffsettransition类的 getOffsetAfter() 方法获取转换发生后第二个偏移区域的偏移值。第一个和第二个偏移量是指创建区域偏移转换对象时传递的值。

语法:

public ZoneOffset getOffsetAfter()

参数:此方法不接受任何参数。

返回值:该方法返回过渡发生后第二个区域偏移的偏移值。它不返回空值。

以下是举例说明 getOffsetAfter() 方法的例子:

例 1:

// Java program to demonstrate
// getOffsetAfter() 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 offset after value
        // by using getOffsetAfter() method
        ZoneOffset off
            = zonetrans1.getOffsetAfter();

        // Display the result
        System.out.println(
            "Zoneoffset after transition : "
            + off);
    }
}

输出:

Zoneoffset after transition : +00:00:12

例 2:

// Java program to demonstrate
// getOffsetAfter() 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 offset after value
        // by using getOffsetAfter() method
        ZoneOffset off
            = zonetrans1.getOffsetAfter();

        // Display the result
        System.out.println(
            "Zoneoffset after transition : "
            + off);
    }
}

输出:

Zoneoffset after transition : +00:00:08
