What are the differences between LocalDate, LocalDateTime, and ZonedDateTime in Java 8?

What are the differences between LocalDate, LocalDateTime, and ZonedDateTime in Java 8?

LocalDate represents a date without time, LocalDateTime includes both date and time, and ZonedDateTime adds time zone information.

Can you give me an example of how to use each of these classes?

Sure! For LocalDate, you can use LocalDate.now() to get the current date. For LocalDateTime, use LocalDateTime.now() for the current date and time. For ZonedDateTime, use ZonedDateTime.now(ZoneId.of("America/New_York")) to get the current date and time in a specific time zone.

What are some common use cases for each of these classes?

LocalDate is great for birthdays or anniversaries, LocalDateTime is useful for timestamps in databases, and ZonedDateTime is ideal for scheduling events across different time zones.

Are there any performance differences between them?

Generally, LocalDate and LocalDateTime are lightweight and faster for operations, while ZonedDateTime may have a slight overhead due to time zone calculations.
