Answer
Final fields prevent reassignment after initialization.
The 'final' keyword ensures that a field can only be assigned once, making it a cornerstone of immutability. In e-commerce, a customer's ID can be a final field since it doesn't change once set. This prevents accidental changes and enforces stability within your application.
