We’ve decoupled the dependencies and are free to test our Windows98Machine with whichever testing framework we choose. If we want, we can easily switch out the type of keyboard in our machine with a different implementation of the interface. Now our classes are decoupled and communicate through the Keyboard abstraction. This principle prevents unnecessary coupling between classes and interfaces, leading to more maintainable and cohesive. In other words, interfaces should be designed to be specific to the needs of the implementing classes. Let’s decouple our machine from the StandardKeyboard by adding a more general Keyboard interface and using this in our class: public interface Keyboard The Interface Segregation Principle states that clients should not be forced to implement interfaces they dont use. Interface Segregation Principle is easy to understand and simple to follow. The Interface Segregation Principle (ISP) states that a class should not be forced to implement interfaces it does not use. Let us understand the Interface segregation principle. Client should not have the dependency on the interfaces that they do not use. At the bare bones, the DIP is a simple yet powerful programming paradigm that we can use to implement well-structured, highly-decoupled, and reusable software components. Interface Segregation Principle states Clients should not be forced to depend upon interfaces that they do not use. The Dependency Inversion Principle (DIP) forms part of the collection of object-oriented programming principles popularly known as SOLID. And we’re stuck with our Monitor class too. Interface segregation principle (ISP) is one of the five principles of SOL I D acronym. The idea is that if the caller of an interface only uses a subset of methods on the interface, it suggests that the interface has too many responsibilities: the ones used by this caller, and the ones that are only used by other callers can be separated. Not only does this make our Windows98Computer hard to test, but we’ve also lost the ability to switch out our StandardKeyboard class with a different one should the need arise. The interface segregation principle is about the interface supplied to clients of a service.
