PezDispenser dispenser = new PezDispenser("Yoda");
System.out.printf("The dispenser is %S %n",

String before = dispenser.swapHead("Darth Vader");

We are making a new Pez dispenser
The dispenser is Yoda
The dispenser is now Darth Vader, but it used to be Yoda
Did you perhaps forget to save your changes or recompile?

231,184 PointsYou have "CharacterName" (capital "C") as the parameter instead of "characterName" (lower-case "c"):
public String swapHead(String CharacterName) {
This causes the method to just assign the current name back to itself instead of the new one.
Personally, I use completely different names for parameters than any private fields to prevent these kinds of things from passing unnoticed by the compiler.
