Why might you choose an interface over an abstract class?

Java: Polymorphism
Answer
Interfaces allow multiple inheritance of type, providing more flexible design options.
Interfaces are chosen over abstract classes when you need a class to implement multiple types, as Java allows classes to implement multiple interfaces but only inherit from one class. For example, a `Product` might implement both `Serializable` and `Comparable` interfaces to support serialization and sorting, while extending a single class like `BaseProduct`.
