LocalTime plusSeconds() method in Java with Examples

The plusSeconds() method of LocalTime class is used to add specified number of seconds value to this LocalTime and return the result as a LocalTime object. This instant is immutable. The calculation wraps around midnight.

Syntax:

public LocalTime plusSeconds(long SecondsToAdd)

Parameters: This method accepts a single parameter SecondsToAdd which is the value of Seconds to be added, it can be a negative value.

Return value: This method returns a LocalTime based on this time with the Seconds added.

Below programs illustrate the plusSeconds() method:

Program 1:

// Java program to demonstrate
// LocalTime.plusSeconds() 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 addition: "
                           + time);

        // add 200 Seconds using plusSeconds()
        LocalTime value = time.plusSeconds(200);

        // print result
        System.out.println("LocalTime after addition: "
                           + value);
    }
}

Output:

LocalTime before addition: 19:34:50.630
LocalTime after addition: 19:38:10.630

Program 2:

// Java program to demonstrate
// LocalTime.plusSeconds() 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 addition: "
                           + time);

        // add -3400 Seconds using plusSeconds()
        LocalTime value = time.plusSeconds(-3400);

        // print result
        System.out.println("LocalTime after addition: "
                           + value);
    }
}

Output:

LocalTime before addition: 01:00:01
LocalTime after addition: 00:03:21
