Question

Do method signatures need to match when applying the Liskov Substitution Principle?

a. Yes
b. No

Answer 1

According to the Liskov Substitution Principle, method signatures should match in both the parent class and the subclass.

Step-by-step explanation:

According to the Liskov Substitution Principle, method signatures should match in both the parent class and the subclass.

For example, let's say we have a parent class 'Shape' with a method 'calculateArea()'. If we have a subclass 'Rectangle' that extends 'Shape', the 'calculateArea()' method should have the same signature in both classes, meaning it should have the same name and the same parameters.

So, the answer is Yes, method signatures do need to match when applying the Liskov Substitution Principle.
