The getNano() method of Duration Class in java.time package is used to get the nanos value of this duration.
Syntax:
public long getNano()
Parameters: This method do not accepts any parameter.
Return Value: This method returns a long value of the nanos of this duration.
Below examples illustrate the Duration.getNano() method:
Example 1:
// Java code to illustrate getNano() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Get the text        String time = "P2DT3H4M";          // Duration using parse() method        Duration duration = Duration.parse(time);          // Get the duration in nanos        // using getNano() method        System.out.println(duration.getNano());    }} |
Output:
0
Example 2:
// Java code to illustrate getNano() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Duration using ofHours() method        Duration duration = Duration.ofHours(5);          // Get the duration in nanos        // using getNano() method        System.out.println(duration.getNano());    }} |
Output:
0
