		LocalDateTime ldTime = LocalDateTime.now();
		System.out.println("Current date time: "+ldTime);

		// add 10 days to current time
		LocalDateTime advLdTime = ldTime.plusDays(10);
		System.out.println("Date time after 10 days: "+advLdTime);

		// add 5 hours to crrent time
		LocalDateTime advLdTime1 = ldTime.plusHours(5);
		System.out.println("Date time after adding 5 hours: "+advLdTime1);

		// date one month before
		LocalDateTime prevLdTime = ldTime.minusMonths(1);
		System.out.println("Date one month before: "+prevLdTime);

		// date two week before
		LocalDateTime prevLdTime1 = ldTime.minusWeeks(2);
		System.out.println("Date two weeks before: "+prevLdTime1);
	}
}

Current date time: 2015-12-16T09:38:15.975
Date time after 10 days: 2015-12-26T09:38:15.975
Date time after adding 5 hours: 2015-12-16T14:38:15.975
Date one month before: 2015-11-16T09:38:15.975
Date two weeks before: 2015-12-02T09:38:15.975

Can interface be final?
No. We can not instantiate interfaces, so in order to make interfaces useful we must create subclasses. The final keyword makes a class unable to be extended.
