LocalTime ofNanoOfDay() method in Java with Examples

The ofNanoOfDay() method of LocalTime class is used to obtain LocalTime Instance from a nanos-of-day value. This returns a LocalTime with the specified the nano of day, from 0 to 24 * 60 * 60 * 1, 000, 000, 000 – 1 passed as parameter.

Syntax:

public static LocalTime ofNanoOfDay(long nanoOfDay)

Parameters: This method accepts a single parameter nanoOfDay which is the nano of day, from 0 to 24 * 60 * 60 * 1, 000, 000, 000 – 1.

Return value: This method returns LocalTime instance created from the nanoOfDay passed as the parameter.

Exception: This method throws DateTimeException if the nanoofDay value passed as the parameter is invalid.

Below programs illustrate the ofNanoOfDay() method:

Program 1:

// Java program to demonstrate
// LocalTime.ofNanoOfDay() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a nano of day
        long nanoofday = 14245000000000l;

        // applying ofNanoOfDay()
        LocalTime value
            = LocalTime.ofNanoOfDay(nanoofday);

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

Output:

LocalTime: 03:57:25

Program 2:

// Java program to demonstrate
// LocalTime.ofNanoOfDay() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a nano of day
        long nanoofday = 5000000000l;

        // applying ofNanoOfDay()
        LocalTime value
            = LocalTime.ofNanoOfDay(nanoofday);

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

Output:

LocalTime: 00:00:05
