Can you explain the Liskov Substitution Principle?
Sure! 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?
Absolutely! Imagine you have a class Bird
with a method fly()
. If you create a subclass Penguin
that cannot fly, substituting Bird
with Penguin
would violate this principle.
How can I ensure my classes follow this principle?
To ensure compliance, make sure that subclasses maintain the behavior expected by the superclass. Avoid overriding methods in a way that changes their expected behavior.
What are the benefits of following the Liskov Substitution Principle?
Following this principle leads to more maintainable and understandable code, as it promotes proper inheritance and reduces bugs.
