Below programs illustrate the LocalDateTime.plusYears() method in Java:

Program 1:  

Java

// Program to illustrate the plusYears() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        LocalDateTime dt1
            = LocalDateTime
                  .parse("2018-01-11T10:15:30");

        System.out.println("LocalDateTime with 15 years added: "
                           + dt1.plusYears(15));
    }
}

Output:

LocalDateTime with 15 years added: 2033-01-11T10:15:30

Program 2:  

Java

// Program to illustrate the plusYears() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        LocalDateTime dt1
            = LocalDateTime
                  .parse("2018-01-11T08:15:30");

        System.out.println("LocalDateTime with -2 years added: "
                           + dt1.plusYears(-2));
    }
}

Output:

LocalDateTime with -2 years added: 2016-01-11T08:15:30
