Encapsulating stock checks within Product centralizes data management and logic.
By placing stock level checks within the Product class, you ensure that all logic related to stock management is centralized, reducing the risk of errors and improving maintainability. This approach leverages encapsulation, a core OOP principle, to protect the internal state and behavior of the Product object. For instance, a method like checkStockAvailability() within the Product class can internally manage the conditions under which stock is considered sufficient, without exposing raw stock data to other classes.
