java.time 包中持续时间类的 withSeconds(长)方法用于获取该持续时间的不可变副本，指定的秒数作为参数传递。

语法:

public Duration withSeconds(long amountOfSeconds)

参数:该方法接受一个参数秒量，即秒量。

返回值:该方法返回一个作为参数传递的持续时间。

以下示例说明了 Duration.withSeconds()方法:

例 1:

// Java code to illustrate withSeconds() method

import java.time.Duration;

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

        // Get the amount of seconds
        long amountOfSeconds = 300;

        // Duration using parse() method
        Duration duration
            = Duration.parse("P2DT3H4M");

        // Get the duration in seconds
        // using withSeconds() method
        System.out.println(duration
                               .withSeconds(amountOfSeconds));
    }
}

输出:

PT5M

例 2:

// Java code to illustrate withSeconds() method

import java.time.Duration;

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

        // Get the amount of seconds
        long amountOfSeconds = 3000;

        // Duration using ofHours() method
        Duration duration
            = Duration.ofHours(5);

        // Get the duration in seconds
        // using withSeconds() method
        System.out.println(duration
                               .withSeconds(amountOfSeconds));
    }
}

输出:

PT50M
