Effective Interface with ISP

Explore how to apply the Interface Segregation Principle to design small, cohesive interfaces in Java. This lesson helps you understand keeping interfaces focused on a single responsibility and how breaking down large interfaces improves code maintainability and clarity using TDD and SOLID principles.

Keeping interfaces effective and focused

In this lesson, we’ll look at a principle that helps us write effective interfaces, known as ISP (Interface Segregation Principle). It advises us to keep our interfaces small and dedicated to achieving a single responsibility. By small interfaces, we mean having as few methods as possible on any single interface.
