Answer
Cannot provide multiple inheritance and may lead to rigidity.
Java's single inheritance model means a class can only extend one abstract class, which might lead to a rigid hierarchy. Unlike interfaces, which allow multiple inheritance, abstract classes can make code less flexible if different classes need to share multiple behaviors. For example, if both `Vehicle` and `Machine` are abstract classes with useful methods, a `Car` class cannot extend both.
