  • Last Updated : 04 Dec, 2018

The toNanoOfDay() method of LocalTime class is used to return the time as nanos of day from this LocalTime.Value returned by this method lie between 0 to 24 * 60 * 60 * 1, 000, 000, 000 – 1.

Syntax:

public long toNanoOfDay()

Parameters: This method accepts no parameters.

Return value: This method returns a the long value which is the nano of day value and is equivalent to this time.

Below programs illustrate the toNanoOfDay() method:



Program 1:




// Java program to demonstrate
// LocalTime.toNanoOfDay() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("19:34:50.63");
  
        // extract nano of day from toNanoOfDay()
        long value = time.toNanoOfDay();
  
        // print result
        System.out.println("Nano of day: "
                           + value);
    }
}
Output:
Nano of day: 70490630000000

Program 2:




// Java program to demonstrate
// LocalTime.toNanoOfDay() method
  
import java.time.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a LocalTime object
        LocalTime time
            = LocalTime.parse("23:21:45.98");
  
        // extract nano of day from toNanoOfDay()
        long value = time.toNanoOfDay();
  
        // print result
        System.out.println("Nano of day: "
                           + value);
    }
}
Output:
Nano of day: 84105980000000
