Do you add objects to an array when using switch statement with a For loop?

I meant....

"HOW" do you add objects to an array....

I have four classes.

Person is the super class, Student, Undergraduate, and PolymorphismExample.

I somewhat understand how to add objects into an array, whoever, I'm not sure how to do it when using inputs in a switch statement contained in a for loop. How would I go about in doing that?

Code :

import java.util.Scanner;                                                                             
 
public	class PolymorphismExample

I'm not sure how to do it when using inputs in a switch statement contained in a for loop.

The location of the assignment statement should not make any difference. If you know how to write a statement to assign a value to an element of an array, you can code that statement in the loop or switch statement
