What role does encapsulation play in method validation?
Multiple choiceMediumchapter-3-curatedpremiumoopinvariants-and-validation
Answer and explanation
Correct answer
A. Encapsulation allows methods to enforce rules on data access
Why
Encapsulation provides a controlled way to access and modify an object's data through methods. This allows methods to enforce rules on data access and validate inputs, ensuring that only valid data affects the object's state, thus maintaining its invariants.
