Java: Code Reading and State Safety
Answer
Setter-heavy designs can lead to fragile and less maintainable code.
Relying heavily on setters can make it easy to create invalid states, as any part of the code can change the object's state at any time. This is problematic in scenarios like an e-commerce application where a `Product` class might have setters for essential properties like `price` and `stock`. Allowing unrestricted changes can lead to inconsistent states, such as negative stock levels or incorrect pricing.
