Java: Object Responsibility
Answer
Private fields prevent direct access, allowing control over how they are modified.
Using private fields ensures that an object's state cannot be changed arbitrarily. It requires developers to use methods to modify fields, which can include necessary validation. For example, a `Cart` class should have private fields for `items` to ensure that items are only added or removed in controlled ways.
