Java: Invariants and Validation
Answer
Constructor validation ensures an object is created in a valid state.
When creating an object, constructor validation checks that the initial values meet any necessary conditions. This prevents creating objects that could lead to errors later. For example, a constructor for an Order class in an e-commerce application might ensure the quantity is positive, avoiding invalid orders.
