Importance of ISP

• Prevents Bloated Classes: By creating smaller, focused interfaces, ISP ensures that classes aren’t forced to implement unnecessary methods.

• Improves Maintainability: Focused interfaces make the code easier to maintain since each class deals only with relevant behaviors.

• Enhances Flexibility: ISP allows for flexible systems where you can easily add or modify functionality without affecting unrelated parts.

• Simplifies Testing: Smaller interfaces mean classes have fewer dependencies, making them easier to test and debug.

• Promotes Clearer Design: ISP leads to cleaner code by encouraging clear boundaries between different functionalities, reducing complexity.

How ISP Relates to Other SOLID Principles

• SRP: ISP supports SRP by keeping interfaces focused on a single responsibility, ensuring that classes implement only what they need.

• OCP: ISP aligns with OCP by making it easy to extend systems with new interfaces without modifying existing ones.

• LSP: ISP helps with LSP because classes implementing smaller interfaces respect their contract, making substitution safer and more predictable.
