Interface Segregation Principle
Welcome to the fourth installment of our five-part series on SOLID principles. In this blog, we’ll deep dive into the ‘I’ in SOLID. Get ready to explore the core concept of the Interface Segregation Principle and discover how it can revolutionize your approach to software development.
The Interface Segregation Principle (ISP) is one of the SOLID principles of object-oriented design. It focuses on keeping interfaces as specific and small as possible, with the goal of reducing the side effects and frequency of changes when implementing interfaces. In simpler terms, it states that no class should be forced to depend on methods it does not use.
No class should be forced to depend on methods it does not use.
Mechanisms to Achieve Interface Segregation Principle:
To adhere to the Interface Segregation Principle, consider the following mechanisms:
1. Multiple Interfaces: Instead of having a single large interface with many methods, create multiple smaller interfaces, each with a specific set of related methods. Classes can then implement only the interfaces that are relevant to them.
2. Default Implementations: In languages that support it, you can provide default method implementations within interfaces. This allows…
