The withSecond() method of a LocalTime class is used to get a copy of this LocalTime with the seconds changed to the seconds 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 withSecond(int second)
Parameters: This method accepts a single parameter second which represents the second-of-minute to set in the result, from 0 to 59.
Return value: This method returns a LocalTime instance based on this time with the requested second.
Exception: This method throws a exception DateTimeException if the second value is invalid
Below programs illustrate the withSecond() method:
Program 1:
// Java program to demonstrate// LocalTime.withSecond() 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 seconds 4        LocalTime newtime = time.withSecond(4);          // print result        System.out.println("New LocalDateTime: "                           + newtime);    }} |
Old LocalTime: 19:34:50.630 New LocalDateTime: 19:34:04.630
Program 2:
// Java program to demonstrate// LocalTime.withSecond() 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 seconds 23        LocalTime newtime = time.withSecond(23);          // print result        System.out.println("New LocalDateTime: "                           + newtime);    }} |
Old LocalTime: 01:21:30.130 New LocalDateTime: 01:21:23.130
