Java 8 Period Class Introduction | Java 8 Date and Time | Java Date and Time
PeriodDemo1.java

import java.time.Period;

public class PeriodDemo1
{

    public static void main(String[] args)
    {
        /*
         * Parameters:
         *
         * years - the amount of years, may be negative
         *
         * months - the amount of months, may be negative
         *
         * days - the amount of days, may be negative
         *
         * Returns:
         *
         * the period of years, months and days, not null
         */

        Period period = Period.of(2017, 02, 16);
        System.out.println("period = " + period);

        /*
         * Returns: the amount of years of this period, may be
         * negative
         */

        System.out.println("Years = " + period.getYears());

        /*
         * Returns: the amount of months of this period, may be
         * negative
         */

        System.out.println("Months = " + period.getMonths());

        /*
         * Returns: the amount of days of this period, may be negative
         */

        System.out.println("Days = " + period.getDays());
    }

}

Output

period = P2017Y2M16D
Years = 2017
Months = 2
Days = 16

PeriodDemo2.java

import java.time.Period;

public class PeriodDemo2
{
    public static void main(String[] args)
    {
        /*
         * A constant for a period of zero.
         */

        Period period = Period.ZERO;

        System.out.println("period = "+period);
    }

}

Output

period = P0D
