Java: Getters and Setters Design

Private fields with public getters protect data while allowing controlled access.

Using private fields and public getters is a common practice in Java to enforce encapsulation. It allows the class to control how its data is accessed and modified. This is crucial in scenarios like an e-commerce application, where a 'Product' class might have a private 'price' field. By using a public getter, you ensure that external code can view the price without directly altering it, maintaining data integrity.
