Topic: OOP
Focus: Object Interaction
Java: Object Interaction
Answer
Directly accessing and modifying another object's fields.
A common mistake is allowing one object to directly modify another's fields, breaking encapsulation. For instance, if `ShoppingCart` directly alters `Product` stock levels, it can lead to errors and tight coupling. Instead, interaction should be through methods that manage the internal state safely.
