Final answer:
Without the specific details of hw5, it's not possible to identify the constraint method of MyRec absent in both driver1 and driver2. Constraint methods typically ensure data integrity in programming, and the missing method could suggest a requirements or test coverage issue.
Step-by-step explanation:
Without access to the specifics of homework 5 (hw5), driver1, and driver2, it's not possible to provide a direct answer to which constraint method of MyRec was not found in both. Generally, in a programming context, constraint methods are used to specify certain conditions that objects or data structures must meet within a software application. In the case of object-oriented programming, these constraints might involve methods ensuring that a class's variables are kept within certain bounds, maintain specific relationships, or follow particular rules during the lifecycle of an object.
If MyRec refers to a class in an assignment, the three constraint methods might be setters, getters, or validation methods that would ensure the integrity of the class's data. Driver1 and driver2 might be two separate implementations or test cases checking the functionality of those constraint methods. The absence of one of these methods in both driver implementations could highlight a difference in requirements or a lapse in test coverage.
