LITERALLY DO ANYTHING INCLUDING NOT TERMINATE
⩥ Postcondition. Answer: -Implementer is responsible for meeting
requirements
-Client can assume that it is being met
-"Ensures clause"
⩥ Override. Answer: -2 methods with same name and parameters, where
one is in the parent class and one is in the child class
