New Date & Time API in Java 8

Question

On this page i read the following:

To do calculations with dates, it is also very easy. Probably the best improvement compared to the current situation with Java < 1.

Answer 1

Advantages of the new date/time API

• The notions of date (LocalDate), time (LocalTime), date&time (LocalDateTime), instant (Instant) are much clearer and correspond to their meaning in common language.
• Intializing date/time to a specific value got easier (method 'of', e.g. LocalDate.of(2016,1,1))
• Dealing with leap years (method isLeapYear) got trivial
• Adding/subtracting dates got very easy. E.g. to reference today in 10 years: LocalDate.now().plusYears(10)
• Month numbering offset adapted to intuition. 'January' is '1' now and not '0' as before

Disadvantages

• Not yet supported by JPA2
• Not yet supported by JSF2
