+) File is read in successfully!
+) Good you did error checking when user wants to add a voter with the same
SSN as one existing voter. It is the same with polling places.
+) Very well done! Program is correct and robust. I wasn’t able to crash
it or get it to misbehave.
-) It would be better if you print out the voters or polling places in a
nice format.Use the String.format()
+) Very nice user interface! But you can still improve it by giving user
information regarding whether or not his/her operation is successful.
Furthermore, if the list is empty, print something to tell the user about it
if he/she would like to list the voters or polling places.
+) Well structured. Good you broke the go() of VoteUI into several pieces
+) Good you have proper comments
+) Good you have all fields private
+) Good naming for methods/variables

the VoteUI, it is not necessary to pass all of them as parameters to the
