Java Duration ofSeconds(long, long)用法及代碼示例

java.time包中的Duration Class的ofSeconds(long，long)方法用於獲取1秒格式的持續時間。在這種方法中，以1秒的格式，即每秒1秒，將秒計算為總秒數。第二個參數nanoAdjustment用於以nanoSeconds單位調整秒數。

用法:

public static Duration ofSeconds(long seconds, long nanoAdjustment)

參數：此方法接受兩個參數：

seconds：秒數。它可以是正數或負數。
nanoAdjustment：這是要在幾秒鍾內進行的調整。

返回值：此方法返回以1秒格式表示時間的Duration。

異常：如果輸入的秒數超過Duration的容量，則此方法將引發ArithmeticException。

以下示例說明了Duration.ofSeconds()方法：

範例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()); 
    } 
}

輸出：

Duration without adjustment:214545
Duration with adjustment:214545

範例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()); 
    } 
}

輸出：

Duration without adjustment:214545
Duration with adjustment:214544
