Description: The Interface Segregation Principle states that no client should be forced to depend on methods it does not use. This principle is fundamental in software design as it promotes the creation of specific and focused interfaces rather than general interfaces that may include unnecessary methods. By applying this principle, the aim is to reduce coupling between components and facilitate code maintainability. Interfaces should be designed in such a way that each client only needs to know the methods it actually requires, which in turn improves code clarity and readability. This approach also encourages code reuse, as it allows different implementations of an interface to adapt to the specific needs of clients without including superfluous functionalities. In languages like Kotlin, PHP, and C++, interface segregation can be easily implemented by creating multiple small and specific interfaces instead of a single large interface. This not only improves code organization but also facilitates refactoring and the application of Clean Code principles, allowing developers to focus on the relevant functionalities for each context.
