What are the best practices for function overriding in programming?

What are the best practices for function overriding in programming?

Function overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass. Best practices include ensuring that the method signature matches, using the @Override annotation for clarity, and maintaining the Liskov Substitution Principle.

Can you explain 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. This means that the subclass should extend the behavior of the superclass without changing its expected behavior.

What are some common mistakes to avoid when overriding functions?

Common mistakes include not using the @Override annotation, changing the method's return type in a way that violates the superclass's contract, and failing to call the superclass method when necessary.

How does function overriding differ from function overloading?

Function overriding occurs when a subclass provides a specific implementation of a method already defined in its superclass, while function overloading allows multiple methods in the same class to have the same name but different parameters.
