The plusNanos() method of LocalTime class used to add specified no of nanoseconds value to this LocalTime and return the result as a LocalTime object. This instant is immutable. The calculation wraps around midnight.
Syntax:
public LocalTime plusNanos(long nanosecondsToAdd)
Parameters: This method accepts a single parameter nanosecondsToAdd which is the value of nanoseconds to be added, it can be a negative value.
Return value: This method returns a LocalTime based on this time with the nanoseconds added.
Below programs illustrate the plusNanos() method:
Program 1:
// Java program to demonstrate// LocalTime.plusNanos() 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"); // print LocalTime System.out.println("LocalTime before add: " + time); // add 34000000 nanoseconds using plusNanos() LocalTime value = time.plusNanos(34000000); // print result System.out.println("LocalTime after add: " + value); }} |
Output:
LocalTime before add: 19:34:50.630 LocalTime after add: 19:34:50.664
Program 2:
// Java program to demonstrate// LocalTime.plusNanos() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse("01:00:01"); // print LocalTime System.out.println("LocalTime before add: " + time); // add -971200000 nanoseconds using plusNanos() LocalTime value = time.plusNanos(-971200000); // print result System.out.println("LocalTime after add: " + value); }} |
Output:
LocalTime before add: 01:00:01 LocalTime after add: 01:00:00.028800
