示例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()); 
    } 
}

輸出：

Duration: PT51H4M
2
183840

示例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()); 
    } 
}

輸出：

Duration: PT240H
