Using the code given as a reference. In the main file personalInfo.java create an ArrayList of person type named infolist. Add 3 person objects, 3 teacher objects and 3 student objects to the ArrayList, then navigate the ArrayList using a loop to print out the info on all 9 people. You can modify the program so it does not require you to get user input using a scanner, you can just create all of the people by passing in the information as parameters: add.infolist(new person(tom , jones , 732-555-5555 , 20 Church Lane ); Make sure you pass the correct parameters for the object you are creating in the correct order.

In the main file personalInfo.java create an ArrayList of person type named infolist.
Add 3 person objects, 3 teacher objects and 3 student objects to the ArrayList, then navigate the ArrayList using a loop to print out the info on all 9 people.
You can modify the program so it does not require you to get user input using a scanner, you can just create all of the people by passing in the information as parameters:
add.infolist(new person(tom , jones , 732-555-5555 , 20 Church Lane );
Make sure you pass the correct parameters for the object you are creating in the correct order.
Given code:

int choice = sc.nextInt();
sc.nextLine();
//switch case
switch (choice){
case 1:
