Summary

Completed

In this module, you learned about default implementations in interfaces, their benefits, and how to define them. You also learned how to use interfaces as method parameters, implement system-defined interfaces, and create flexible and reusable code. Additionally, you explored a practical scenario where you designed and implemented various types of lights with different functionalities using interfaces in C#.

After completing this module, you're now able to:

• Define and use default implementations in interfaces.
• Understand the benefits of default implementations, including code reuse, backward compatibility, and flexibility.
• Use interfaces as method parameters to promote loose coupling and enhance testability.
• Implement common system-defined interfaces such as IComparable, IEnumerable, and IDisposable.
• Override default implementations in specific classes to provide custom behavior.
