Java: Fields and State
Answer
Private fields enhance encapsulation. Frame the concept in practical terms so you can explain it during interview discussion.
Encapsulation is a core principle of OOP, promoting hiding object details and exposing only necessary interfaces. Private fields prevent external classes from directly modifying an object's state, reducing the risk of unintended behavior. For example, a Customer class might have private fields for name and email, accessed through public methods.
