What are immutable objects in Java 8's Date and Time API?

In Java 8, the Date and Time API introduced immutable objects like LocalDate, LocalTime, and LocalDateTime. These objects cannot be modified after they are created, ensuring thread safety and reducing bugs.

Can you give me an example of how to create a LocalDate object?

Sure! You can create a LocalDate object using the static method LocalDate.now() for the current date or LocalDate.of(year, month, day) for a specific date.

What are the benefits of using immutable objects?

The benefits include thread safety, easier reasoning about code, and the ability to use objects in functional programming without worrying about their state changing.

How do immutable objects affect performance?

Immutable objects can improve performance in concurrent applications since they can be shared freely without synchronization. However, they may require more memory due to the creation of new instances for modifications.
