Instant 类的 plusSeconds() 方法将作为参数传递的秒值添加到该瞬间，并将结果作为即时对象返回。这个返回的即时消息是不可变的。

public Instant plusSeconds(long secondsToAdd)

参数:该方法接受一个参数秒添加，即秒添加。

返回:此方法在加上秒后返回瞬间。

异常:如果结果超过最大或最小瞬间，该方法抛出以下异常:

  • 日期时间异常:。
  • Arithmetic exception: If there is a numerical overflow.

下面的程序说明了 plusSeconds()方法:

程序 1:

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

import java.time.*;

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

        // create a Instant object
        Instant instant
            = Instant.parse("2018-10-28T19:34:50.63Z");

        // print Instant
        System.out.println("Instant: "
                           + instant);

        // addition of 84000 seconds to this instant
        Instant returnedValue
            = instant.plusSeconds(84000);

        // print result
        System.out.println("Returned Instant: "
                           + returnedValue);
    }
}

输出:

Instant: 2018-10-28T19:34:50.630Z
Returned Instant: 2018-10-29T18:54:50.630Z

程序二:

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

import java.time.*;

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

        // create a Instant object
        Instant instant = Instant.now();

        // current Instant
        System.out.println("Current instant: "
                           + instant);

        // addition of 930000 seconds
        // to this instant
        Instant returnedValue
            = instant.plusSeconds(930000);

        // print result
        System.out.println("Returned Instant: "
                           + returnedValue);
    }
}

输出:

Current instant: 2018-11-28T05:39:46.572Z
Returned Instant: 2018-12-08T23:59:46.572Z
