Java: Fields and State
Answer
Final fields make a class's state immutable, enhancing consistency.
Declaring fields as final ensures they can only be set once, typically during object construction. This immutability guarantees consistent state, reducing bugs. In a Customer class, making 'email' final ensures it remains unchanged, preserving identity.
