Answer
Private fields ensure data integrity by preventing unauthorized access.
By declaring fields as private, Java classes limit direct access to their internal state, which helps maintain control over how data is modified. In an e-commerce application, a `User` class might keep its password field private and provide methods for setting or validating the password to ensure security protocols are followed.
