Duration toNanosPart() method in Java with Examples

Last Updated : 26 Nov, 2018

The toNanosPart() method of Duration Class in java.time package is used get the nanoseconds part within seconds of the duration.

Syntax:

public long toNanosPart()

Parameters: This method do not accepts any parameter.

Return Value: This method returns a long value which is the nanoseconds part within seconds of the duration.

Below examples illustrate the Duration.toNanosPart() method:

Example 1:

// Java code to illustrate toNanosPart() 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 nano-seconds 
        // using toNanosPart() method 
        System.out.println(duration.toNanosPart()); 
    } 
} 

Output:

Duration: PT51H4M
0

Example 2:

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