Java 8 Period example.


The Period class represents a quantity of time in terms of years, months and days. A Period uses date based values (years, months, days).

PeriodEx
package com.java2novice.datetime;

import java.time.LocalDate;
import java.time.Period;

public class PeriodEx {

	public static void main(String a[]) {

		// get current date
		LocalDate currTime = LocalDate.now();
		System.out.println("current date: "+currTime);

		// add 10 days to the current date time
		LocalDate dateAfter10Days = currTime.plus(Period.ofDays(10));
		System.out.println("date after 10 days: "+dateAfter10Days);

		// what is the date a week before
		LocalDate dateBeforeWeek = currTime.minus(Period.ofWeeks(3));
		System.out.println("date before 3 week: "+dateBeforeWeek);

		// no of days between two dates
		Period periofDiff = Period.between(dateBeforeWeek, dateAfter10Days);
		System.out.println("day difference: "+periofDiff.getDays());
		System.out.println("months difference: "+periofDiff.getMonths());
	}
}

Output:
current date: 2016-12-15
date after 10 days: 2016-12-25
date before 3 week: 2016-11-24
day difference: 1
months difference: 1
