How do you know which characterName this.characterName refers to????

I had assumed it would always refer to the characterName we'd just typed in the brackets at 2.06 he says it refers to the characterName in line 2. Does it always refer to the first one declared or something?

Since the function has a parameter named "characterName", that will refer to the parameter when used by itself. But when you reference "this.characterName", it refers to the class variable defined on line 2.

Putting a "this." prefix on a name refers to something in the class rather than a local variable of parameter of the method.
