Answer
Ensure the subclass methods fulfill the same contract as the superclass methods.
To adhere to the Liskov Substitution Principle, overridden methods should not change the expected behavior of the superclass methods. For example, if the superclass method is expected to return a positive price, the overridden method in a subclass should also guarantee this.
