参数。该方法接受一个参数 amountOfSeconds，它是秒数的数量。

返回值。该方法返回一个以参数形式传递的秒数的Duration。

下面的例子说明了Duration.withSeconds()方法。

例子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:
