If e1.e = e3 and e3 is later set to null, this means that e1.e = null right?
No. Of course not. When you set the e1.e reference to point to the same object as the e3 reference, they are two different references that point to the same object. It doesn't tie the two references together, to be always pointing to the same thing.

Just reading through the access modifiers and almost done with Chapter one. Just curious as to why you would want to use the protected access modifier from a practical standpoint. Can anyone think of a real world example of why we would use this?

You are not allowed calculators, cell phones, wallets, papers, pens, etc.. You would be lucky to get a rest room break if you are polite to the testing center.
I say call few days ahead, say who you are and what test you will be taking. That helps to create rapport.
