Java: Invariants and Validation
Answer
It ensures only valid operations are allowed.
Method validation checks the inputs and conditions before performing operations, thus maintaining the integrity of the encapsulated data. In a `Cart` class, validating item quantities before adding them to the cart prevents the inclusion of negative amounts, upholding business rules and data correctness.
