Track: Java
Topic: OOP
Focus: Fields and State
Java: Fields and State
Answer
To protect data and provide controlled access.
Private fields prevent direct access, while public methods offer controlled interactions. This protects the integrity of an object’s state. For example, a Customer class might have private fields for sensitive data, with public methods for updates, ensuring validation and constraints are applied.
