823 PointsCan 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?

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 swapHead
method.
So before
equals "Yoda" and dispenser.getCharacterName()
equals "Darth Vader".
