Hard
Given a class A that implements a method to record the values of the class members in a database. Given a class A1 that inherits from A and a class A2 that also inherits from A.
You must develop as quickly as possible, and with the least code possible, a program that allows the recording of the data of an instance A, an instance A1 or an instance A2 in a database. How will you proceed? (two choices required)
