Can someone please explain the order of this code?
String before = dispenser.swapHead("Darth Vader"); System.out.printf ("It was %s but Chris switched it to %s %n", before, dispenser.getCharacterName());
Here, before refers to Darth Vader and dispenser.getCharacterName() refers to Yoda. So the output should be " It was Darth Vader but Chris switched it to Yoda" but instead the output is "It was Yoda but Chris switched it to Darth Vader." WHY?
Because you are incorrect about what the variables store.
before stores what the
dispenser.swapHead("Darth Vader") call returns. That method returns the name the dispenser had before it was switched.
dispenser.getCharacterName() returns the current name of the dispenser, which was changed to "Darth Vader" by the
before equals "Yoda" and
dispenser.getCharacterName() equals "Darth Vader".
