Better Ways to Access Parent Properties in Deeply Nested Class Hierarchies

In object-oriented programming, deeply nested class hierarchies often force developers to pass entire parent objects into child methods just to retrieve a single property. This practice violates encapsulation, bloats method signatures, and creates tight coupling between classes. The core problem is the absence of a clean mechanism for child classes to access ancestor properties without receiving full object references. Design patterns such as dependency injection and composition over inheritance offer more elegant alternatives to this brute-force approach. Addressing these structural issues improves code readability, maintainability, and scalability in complex systems.
