Java: Object Interaction
Answer
Through method calls and references. Frame the concept in practical terms so you can explain it during interview discussion.
In an e-commerce model, `CartItem` references a `Product` object to access its data. Information flows through method calls, such as using `getPrice()` on a `Product` object to get the price within `CartItem`. This method-based access maintains encapsulation and ensures data consistency.
