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

// 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 secondvalue
        // using getNano()
        int value = instant.getNano();

        // print result
        System.out.println("nanoseconds value: "
                           + value);
    }
}

Output:

nanoseconds value: 630000000

Program 2:

Java

// 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 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
