Answer
Mixing public fields and methods breaks encapsulation.
When a class uses both public fields and public methods, it leads to an inconsistent design where some parts of the state can be accessed directly, while others are accessed through methods. This can create confusion and unintended side effects. For example, if a Product class exposes a public stock field but uses a method to update price, the state management becomes inconsistent and error-prone.
