Instant getNano() method in Java with Examples

The getNano() method of Instant class is used to return the number of nanoseconds later in the time-line represented in this instant, from the start of the second. The nanosecond-of-second value which measures the total number of nanoseconds from the second value returned by getEpochSecond().

Syntax:

public int getNano()

Returns: This method returns the nanoseconds within the second value which is always positive and never exceeds 999, 999, 999.

Below programs illustrate the getNano() method:

Program 1:

// Java program to demonstrate 
// Instant.getNano() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a Instant object 
        Instant instant 
            = Instant.parse("2018-12-30T19:34:50.63Z"); 
  
        // get nano second of second secondvalue 
        // using getNano() 
        int value = instant.getNano(); 
  
        // print result 
        System.out.println("nanoseconds value: "
                           + value); 
    } 
} 

Output:

nanoseconds value: 630000000

Program 2:

// Java program to demonstrate 
// Instant.getNano() method 
  
import java.time.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create a Instant object 
        Instant instant = Instant.now(); 
  
        // current Instant 
        System.out.println("Current Instant:"
                           + instant); 
  
        // get nano second of second secondvalue 
        // using getNano() 
        int value = instant.getNano(); 
  
        // print result 
        System.out.println("nanoseconds value: "
                           + value); 
    } 
} 

Output:

Current Instant:2018-11-27T04:21:27.029Z
nanoseconds value: 29000000
