Jeremy wrote X = x; and Y = y; why didn't he define X and Y as an integer or double? X, Y and Z are always numbers right?
And what exactly is a constructor? Im a bit confused over the constructor bit ;/

"X", "Y", and "Z" are just variable names, nothing special and not required to be any specific type.
And a constructor is a special method that runs automatically when you create an instance of a class. It will typically establish initial states such as setting up variables as is being done here.
