Final answer:
The preconditions for a method do not need to be greater than the parent method when applying the Liskov Substitution Principle.
Step-by-step explanation:
The Liskov Substitution Principle is a fundamental principle in object-oriented programming. According to this principle, a subclass should be able to substitute for its superclass without affecting the correctness or behavior of the program. This means that the preconditions of the subclass method should not be greater than the preconditions of the parent method. In other words, the expectations for the inputs and behavior of the subclass method should be no more restrictive than the expectations set by the parent method.
For example, if a parent method expects an integer input, the subclass method should also expect an integer input, but it can also accept other child-specific inputs if needed. However, the subclass method should not expect an input that is more restrictive, such as only accepting even numbers when the parent method accepts any integer.
Therefore, the answer to the question is No. Preconditions for a method do not need to be greater than the parent method when applying the Liskov Substitution Principle.
