Non-Generic Interfaces
Non-generic interfaces are a programming concept, particularly in object-oriented languages like C# and Java, that define a contract of methods, properties, events, or indexers without using type parameters. They specify what members a class must implement, enabling polymorphism and decoupling code from specific implementations. This allows for flexible, reusable designs where different classes can adhere to the same interface while providing their own logic.
Developers should learn non-generic interfaces to enforce consistent behavior across unrelated classes, facilitating code maintainability and testability through dependency injection and mocking. They are essential in scenarios like plugin architectures, where multiple components must implement a standard set of operations, or in design patterns such as Strategy or Observer to decouple algorithms and event handling from concrete classes.
