What are some real-world examples of software design principles?

What are some real-world examples of software design principles?

Sure! One example is the Single Responsibility Principle, which states that a class should have only one reason to change. For instance, in a web application, you might have a User class that handles user data, while a separate Notification class manages user notifications.

Can you give me another example?

Absolutely! The Open/Closed Principle is another key design principle. It suggests that software entities should be open for extension but closed for modification. A good example is using interfaces in Java, where you can add new implementations without changing existing code.

What about the Liskov Substitution Principle?

Great question! The Liskov Substitution Principle states that objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program. For example, if you have a class Bird and a subclass Penguin, you should be able to use Penguin wherever Bird is expected, without issues.

How do these principles help in software development?

These principles help create more maintainable, scalable, and robust software. By following them, developers can reduce bugs, improve code readability, and make it easier to implement changes.
