Java: Composition vs Inheritance
Answer
They can lead to fragile and tightly-coupled code.
Deep inheritance hierarchies can become brittle as changes in a superclass can have unexpected effects on subclasses. This makes the code difficult to maintain and extend. For example, modifying a base class 'Animal' might unintentionally affect classes like 'Dog' and 'Cat', leading to bugs.
