Overall I understand the lesson. Just curious why this:
String before = dispenser.swapHead ("Darth Vader");
still gives an output "Yoda" when we define in printf method one variable as "before" shouldnt it be "Darth Vader" since this string = swapHead method that changes character name?

I suspect the variable being assigned was given the name "before" to indicate that it will be storing the name that was used before the switch. This is useful for creating the message that will show both the original name and what it was switched to.

231,271 PointsThe variable is assigned in the code, on line 10 (the line shown in the question). I'm not sure what you mean by "come out of nowhere".
