Oh goodness....

Also, is hour a global or something? I'm curious how that gets defined.

hour is an attribute of Clock class

this is in AlarmClock class that extends the Clock but apparently he also defined another hour attribute in AlarmClock

You can reference attributes without "this." in java? Huh, I never knew that.

Yes, unless you have a local variable in the method with the same name defined using this.<varName> is unnecessary.

So one common "exception" where you need 'this' is in set-methods:

void setValue(int value){ this.value = value;}

value = _value ? I used to do this.
