Java: Invariants and Validation
Answer
They ensure object correctness from creation.
Constructor validations check the initial values assigned to an object's fields, guaranteeing that the object is valid as soon as it is instantiated. For a `Product` class, ensuring a non-negative price during construction prevents creating products with invalid prices, maintaining system reliability from the start.
