How does immutability in Java Records benefit data integrity?

Answer
Fields in a record are final, ensuring immutability.
In Java Records, fields are implicitly final, meaning once a record instance is created, its fields cannot be changed. This immutability guarantees that data remains consistent and unchanged, which is particularly beneficial in multi-threaded environments. For example, in an e-commerce application, a record `Order(int id, List items)` ensures that once an order is created, the list of items in the order cannot be altered.
