Answer
Private fields restrict access to within the class, enforcing encapsulation.
Using the private keyword on fields ensures that they cannot be accessed directly from outside the class. This allows the class to control how its data is accessed and modified through methods. In an e-commerce setting, making a Product's price field private prevents direct access, ensuring price changes are validated through a setter method.
