Java 8 Date&Time benefits
summary
Demos show concrete Java 8 classes and fixes: use LocalDate.of, LocalTime and LocalDateTime for clear construction and default ISO toString output; use ChronoUnit.DAYS.between or Period/Duration for accurate differences; use plusDays/minusDays for immutable, predictable mutation. Old Calendar/Date behavior is shown failing — setters delay mutation and produce surprising results — while java.time classes produce correct zone-aware conversions with ZoneId/ZoneOffset and clear rules. Slides and code demo available.
