Java 中的 OffsetTime plusSecond()方法，示例

原文:https://www . geeksforgeeks . org/offsettime-plussecond-method-in-Java-with-examples/

偏移时间类的 plusSeconds() 方法用于将指定的秒数值添加到该偏移时间，并将结果作为偏移时间对象返回。这一瞬间是不可改变的。计算大约在午夜进行。

语法:

public OffsetTime plusSeconds(long SecondsToAdd)

参数:此方法接受单个参数秒添加，即要添加的秒值，可以是负值。

返回值:该方法根据该时间返回一个偏置时间，并加上秒数。

下面的程序说明了 plusSeconds()方法:

程序 1:

// Java program to demonstrate
// OffsetTime.plusSeconds() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a OffsetTime object
        OffsetTime time
            = OffsetTime.parse("21:15:10+11:10");

        // print OffsetTime
        System.out.println("OffsetTime before addition: "
                           + time);

        // add 200 Seconds using plusSeconds()
        OffsetTime value = time.plusSeconds(200);

        // print result
        System.out.println("OffsetTime after addition: "
                           + value);
    }
}

输出:

OffsetTime before addition: 21:15:10+11:10
OffsetTime after addition: 21:18:30+11:10

程序二:

// Java program to demonstrate
// OffsetTime.plusSeconds() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a OffsetTime object
        OffsetTime time
            = OffsetTime.parse("14:25:10+01:10");

        // print OffsetTime
        System.out.println("OffsetTime before addition: "
                           + time);

        // add -3400 Seconds using plusSeconds()
        OffsetTime value = time.plusSeconds(-3400);

        // print result
        System.out.println("OffsetTime after addition: "
                           + value);
    }
}

输出:

OffsetTime before addition: 14:25:10+01:10
OffsetTime after addition: 13:28:30+01:10
