Java: Composition vs Inheritance
Answer
A hierarchy that easily breaks with changes in its base classes.
A brittle hierarchy is an inheritance structure where changes to a base class can lead to unintended consequences in derived classes. This makes the code fragile and difficult to maintain. For example, altering the 'printDetails()' method in a 'Product' class might disrupt subclasses like 'Electronics' and 'Clothing' if they rely on the original implementation.
