LocalTime ofNanoOfDay() method in Java with Examples
  • Last Updated : 04 Dec, 2018

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
