Java: Fields and State
Answer
Private fields encapsulate data, preventing unauthorized access and modification.
Encapsulation hides an object's internal state and requires external interaction through methods, such as getters and setters. This control can prevent invalid data states. In a Product class, marking 'price' as private ensures it can only be changed using a controlled method, allowing validation.
