No, it is not breaking anything. Your individual functionalities are supporting OCP and that is the main goal. How you decide in the consumer part which one to use has nothing with the Strategy pattern. Whether you use if or switch or factory pattern, this is up to you.

Great article, thanks! But the question is: in the main method, I still have to do an if or switch to choose which strategy to choose. And this violates the principle of OCP SOLID. How can this be eliminated?

Thanks again Marinko! This is the second pattern that I’ve learned from you. The article is concise and well written. Also, I appreciate the github page option that allows for downloading the code so I can try things for myself. I’m convinced that your articles is the easiest path to learning various design pattern. I’ve read at least from four other design pattern articles.

Hello Satya. I haven’t been using the Unity for the IOC but the base logic should be the same. First, you need to register the JuniorDevSalaryCalculator and SeniorDevSalaryCalculator with the ISalaryCalculator interface. After that you should register the SalaryCalculator class because it expects ISalaryCalculator as a parameter in the constructor. After that, you should be able to use SalaryCalculator object in your project.

Marinko,
How I’m going to inject it using any IOC container?
I tried using Unity not able to resolve the injection.

In reply to Satya!.

You are already using DI. Take a look at the SalaryCalculator class, you are injecting any object of type ISalaryCalculator in the constructor (this means that you can send either SeniorDevSalaryCalculator or JuniorDevSalaryCalculator class or any other class that implements ISalaryCalculator interface).

How do I do dependency injection for this?
