    Default 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?


    import java.util.Scanner;                                                                             
     
    public	class PolymorphismExample                                                                     
    {                                                                                                     
     
    	public static void main(String[] args)                                                            
    	{

    			userInput = keyboard.next().charAt(0);
     
    				switch(userInput)

    			}

    }


    The ultimate goal is to get to here....


    Enter the type of person: P
    Enter a name: Philip Rivers

    Enter the type of person: U
    Enter a name: Vincent Jackson
    Enter a student number: 83

    Enter the type of person: P
    Enter a name: Ryan Mathews

    Enter the type of person: S
    Enter a name: Antonio Gates
    Enter a student number: 85

    Name: Philip Rivers

    Person 2:
    Name: Vincent Jackson
    Student Number: 83
    Student Level: 3

    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
