LocalTime withSecond() method in Java with Examples

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);
    }
}

Output:

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);
    }
}

Output:

Old LocalTime: 01:21:30.130
New LocalDateTime: 01:21:23.130
