What is the Liskov Substitution Principle?
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.
Can you give me an example of this principle in action?
Sure! If you have a class Bird
and a subclass Penguin
, you should be able to use a Penguin
wherever a Bird
is expected, without causing errors.
What are the benefits of following this principle?
Following the Liskov Substitution Principle enhances code reusability and maintainability, making your codebase more robust.
Are there any common pitfalls to avoid?
Yes, a common pitfall is violating the principle by introducing subclasses that do not fulfill the expected behavior of the superclass.
