java.time包中Duration类的toDaysPart()方法是通过用秒数除以86400来获取该期限的天数。

语法。

public long toDaysPart()

参数。此方法不接受任何参数。

返回值。该方法返回一个长值，即用秒数除以86400，得出该持续时间内的天数。

下面的例子说明了Duration.toDaysPart()方法。

例1:

// Java code to illustrate toDaysPart() method
  
import java.time.Duration;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Duration using parse() method
        Duration duration
            = Duration.parse("P2DT3H4M");
  
        System.out.println("Duration: "
                           + duration);
  
        // Get the number of days
        // using toDaysPart() method
        System.out.println(duration.toDaysPart());
    }
}

输出:

Duration: PT51H4M
2
183840

例2:

// Java code to illustrate toDaysPart() method
  
import java.time.Duration;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Duration using ofDays() method
        Duration duration
            = Duration.ofDays(10);
  
        System.out.println("Duration: "
                           + duration);
  
        // Get the number of days
        // using toDaysPart() method
        System.out.println(duration.toDaysPart());
    }
}
