LocalDateTimeDemo.java

import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;

public class LocalDateTimeDemo
{

    public static void main(String[] args)
    {
        LocalDateTime currentDatetime = LocalDateTime.now();
        System.out.println("currentDatetime= " + currentDatetime);

        /*
         * Parameters:
         *
         * amountToAdd - the amount of the unit to add to the result,
         * may be negative
         *
         * unit - the unit of the amount to add, not null
         *
         * Returns:
         *
         * a LocalDateTime based on this date-time with the specified
         * amount added, not null
         */
        LocalDateTime localDateTime2 = currentDatetime.plus(5,
                ChronoUnit.MONTHS);
        System.out.println("Month Added    = " + localDateTime2);

        /*
         * Parameters:
         *
         * amountToSubtract - the amount of the unit to subtract from
         * the result, may be negative
         *
         * unit - the unit of the amount to subtract, not null
         *
         * Returns:
         *
         * a LocalDateTime based on this date-time with the specified
         * amount subtracted, not null
         */

        LocalDateTime localDateTime3 = currentDatetime.minus(5,
                ChronoUnit.YEARS);
        System.out.println("Years reduced  = " + localDateTime3);
    }

}

Output

currentDatetime= 2018-01-16T09:44:12.673
Month Added    = 2018-06-16T09:44:12.673
Years reduced  = 2013-01-16T09:44:12.673
