Java Duration ofSeconds(long, long)用法及代码示例

java.time包中的Duration Class的ofSeconds(long，long)方法用于获取1秒格式的持续时间。在这种方法中，以1秒的格式，即每秒1秒，将秒计算为总秒数。第二个参数nanoAdjustment用于以nanoSeconds单位调整秒数。

用法:

public static Duration ofSeconds(long seconds, long nanoAdjustment)

参数：此方法接受两个参数：

seconds：秒数。它可以是正数或负数。
nanoAdjustment：这是要在几秒钟内进行的调整。

返回值：此方法返回以1秒格式表示时间的Duration。

异常：如果输入的秒数超过Duration的容量，则此方法将引发ArithmeticException。

以下示例说明了Duration.ofSeconds()方法：

范例1：

// Java code to illustrate ofSeconds() method 
  
import java.time.Duration; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // input number of Seconds 
        long noOfSeconds = 214545; 
  
        // input nanoSeconds adjustment to be made 
        long nanoSecAdjust = 10000; 
  
        // Duration using ofSeconds() method 
        Duration duration 
            = Duration.ofSeconds(noOfSeconds); 
        Duration duration1 
            = Duration.ofSeconds(noOfSeconds, 
                                 nanoSecAdjust); 
  
        System.out.println("Duration without adjustment:"
                           + duration.getSeconds()); 
        System.out.println("Duration with adjustment:"
                           + duration1.getSeconds()); 
    } 
}

输出：

Duration without adjustment:214545
Duration with adjustment:214545

范例2：

// Java code to illustrate ofSeconds() method 
  
import java.time.Duration; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // input number of Seconds 
        long noOfSeconds = 214545; 
  
        // input nanoSeconds adjustment to be made 
        long nanoSecAdjust = -10000; 
  
        // Duration using ofSeconds() method 
        Duration duration 
            = Duration.ofSeconds(noOfSeconds); 
        Duration duration1 
            = Duration.ofSeconds(noOfSeconds, 
                                 nanoSecAdjust); 
  
        System.out.println("Duration without adjustment:"
                           + duration.getSeconds()); 
        System.out.println("Duration with adjustment:"
                           + duration1.getSeconds()); 
    } 
}

输出：

Duration without adjustment:214545
Duration with adjustment:214544
