Description: Default interface methods in Java are a feature that allows interfaces to define methods with a concrete implementation. This means that, unlike traditional interfaces that can only declare methods without implementation, Java allows providing default behaviors that the classes implementing the interface can use or override. This functionality enhances code flexibility and reuse, as it enables developers to add new methods to interfaces without breaking existing implementations. Moreover, default methods facilitate the creation of cleaner and more organized class hierarchies, allowing interfaces to act as contracts that can include common logic. This feature aligns with the modern approach to object-oriented programming, where modularity and reuse are essential for efficient software development.
