Java: Access Modifiers and Visibility
Answer
They expose internal state directly. Frame the concept in practical terms so you can explain it during interview discussion.
Public fields can be accessed and modified freely, which breaks encapsulation. For instance, if a 'Product' class has a public 'int stock', any class can change the stock count without validation, potentially causing inventory inconsistencies.
