LocalDateTime plusYears() method in Java

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

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 2 years added is: " + ldt.plusYears(2));
   }
}

Output

The current LocalDateTime is: 2019-02-18T10:20:27.152
The LocalDateTime with 2 years added is: 2021-02-18T10:20:27.152

Now let us understand the above program.

First the current LocalDateTime is displayed. Then an immutable copy of the LocalDateTime where 2 years are added is obtained using the plusYears() 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 2 years added is: " + ldt.plusYears(2));
