The withNano() method of a LocalTime class is used to get a copy of this LocalTime with the nanos changed to the nanos passed as the parameter to this method. The remaining values of this LocalTime will remain the same. This instance is immutable and unaffected by this method call.
Syntax:
public LocalTime withNano(int nano)
Parameters: This method accepts a single parameter nano which represents the nano-of-second to set in the result, from 0 to 999, 999, 999.
Return value: This method returns a LocalTime instance based on this time with the requested nano.
Exception: This method throws a exception DateTimeException if the nano value is invalid
Below programs illustrate the withNano() method:
Program 1:
// Java program to demonstrate// LocalTime.withNano() 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 time System.out.println("Old LocalTime: " + time); // Get a new LocalDateTime with nanos 100000 LocalTime newtime = time.withNano(100000); // print result System.out.println("New LocalDateTime: " + newtime); }} |
Old LocalTime: 19:34:50.630 New LocalDateTime: 19:34:50.000100
Program 2:
// Java program to demonstrate// LocalTime.withNano() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse("01:21:30.13"); // print time System.out.println("Old LocalTime: " + time); // Get a new LocalDateTime with nanos 999999 LocalTime newtime = time.withNano(999999); // print result System.out.println("New LocalDateTime: " + newtime); }} |
Old LocalTime: 01:21:30.130 New LocalDateTime: 01:21:30.000999999
