Instant Class getNano() method

• getNano() method is available in java.time package.
• getNano() method is used to get the number of nanoseconds in a second from this Instant.
• getNano() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• getNano() method does not throw an exception at the time of returning nanoseconds.

Syntax:

    public int getNano();

Parameter(s):

• None

Return value:

The return type of this method is int, it returns the number of nanoseconds within the second from this Instant.

Example:

// Java program to demonstrate the example 
// of getNano() method of Instant

import java.time.*;

public class GetNanoOfInstant {
    public static void main(String args[]) {
        // Instantiates two Instant
        Instant ins1 = Instant.parse("2006-04-03T05:10:15.20Z");
        Instant ins2 = Instant.now();

        // Display ins1,ins2
        System.out.println("Instant ins1 and ins2: ");
        System.out.println("ins1: " + ins1);
        System.out.println("ins2: " + ins2);

        System.out.println();

        // Here, this method gets the number of
        // nanoseconds in a second from
        // this Instant ins1
        int get_val = ins1.getNano();

        // Display get_val
        System.out.println("ins1.getNano(): " + get_val);

        // Here, this method gets the number of
        // nanoseconds in a second from
        // this Instant ins2
        get_val = ins2.getNano();

        // Display get_val
        System.out.println("ins2.getNano(): " + get_val);
    }
}

Output

Instant ins1 and ins2: 
ins1: 2006-04-03T05:10:15.200Z
ins2: 2020-05-25T22:25:42.302227Z

ins1.getNano(): 200000000
ins2.getNano(): 302227000
