# LocalDateTime plusSeconds() method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of a LocalDateTime object where some seconds are added to it can be obtained using the plusSeconds() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the number of seconds to be added and it returns the LocalDateTime object with the added seconds.

A program that demonstrates this is given as follows −

## Example

Live Demo

import java.time.*;
public class Demo {
public static void main(String[] args) {
LocalDateTime ldt = LocalDateTime.now();
System.out.println("The current LocalDateTime is: " + ldt);
System.out.println("The LocalDateTime with 5 seconds added is: " + ldt.plusSeconds(5));
}
}

## Output

The current LocalDateTime is: 2019-02-16T11:36:22.428
The LocalDateTime with 5 seconds added is: 2019-02-16T11:36:27.428

Now let us understand the above program.

First the current LocalDateTime is displayed. Then an immutable copy of the LocalDateTime where 5 seconds are added is obtained using the plusSeconds() method and this is displayed. A code snippet that demonstrates this is as follows −

LocalDateTime ldt = LocalDateTime.now();
System.out.println("The current LocalDateTime is: " + ldt);
System.out.println("The LocalDateTime with 5 seconds added is: " + ldt.plusSeconds(5));
