Help with program logic
So I'm currently doing an exercise for OOP, where I'm designing a database for a classroom of students.
So basically I just have two objects "Student" and "Classroom" with specific behaviours like adding a student or removing a student, etc...
For context related to my question, the "Student" class has 5 attributes to it being:
- Student ID
- Student social security number
- Student's name
- Date of birth
- City of birth
Note: every parameters name in the screenshot is also mentioned in this order (ID is excluded)
The main thing I want to ask here is:
I'm trying to implement this new behaviour in the Student class where I can update a student's credentials (Student's ID can not be changed).
I know that sometimes, we only need to update a few information like their name and birthday or sometimes all of their credentials (except the ID)
At first, I thought I can declare all of the parameters and set a default value for them so any credentials that need not be updated can be left blank (as in not inputted when calling this method).
However, I then realise that it was not that simple since I have a case where I need to update the security number and birthdate, but not their name or birthplace. So calling the method as
would not work, since the
Another solution that I came up with this is to overload this method with all of the possible combinations, but then that would mean I need to have (2^4 - 1)
I need some suggestions on what to do here in this case.
Code is not written in english so please excuse the inconvenience
