LocalTime plus() method in Java

An immutable copy of a LocalTime where the required duration is added to it can be obtained using the plus() method in the LocalTime class in Java. This method requires two parameters i.e. the duration to be added and the TemporalUnit of the duration. Also, it returns the LocalTime object with the required duration added to it.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.time.*;
import java.time.temporal.*;
public class Demo {
   public static void main(String[] args) {
      LocalTime lt = LocalTime.now();
      System.out.println("The LocalTime is: " + lt);
      System.out.println("The LocalTime after adding 30 minutes is: " + lt.plus(30, ChronoUnit.MINUTES));
   }
}

Output

The LocalTime is: 06:44:51.447
The LocalTime after adding 30 minutes is: 07:14:51.447

Now let us understand the above program.

First the LocalTime is displayed. Then an immutable copy of the LocalTime where 30 minutes are added to it is obtained using the plus() method and this is displayed. A code snippet that demonstrates this is as follows −

LocalTime lt = LocalTime.now();
System.out.println("The LocalTime is: " + lt);
System.out.println("The LocalTime after adding 30 minutes is: " + lt.plus(30, ChronoUnit.MINUTES));
