("It was %s but chris switched it to %s",before,dispenser.getCharacterName);

So, we are using two %s here.. %s - Yoda - dispenser.getCharacterName

%s - Darth Vader - before

My Question is HOW did YODA come first@(It was %s) when before is used in the statement and then comes dispenser.getCharacterName...

Is it not supposed to be "It was Darth vader but chris switched it to Yoda"

OUTPUT It was Yoda but chris switched it to Darth Vader

That was because the function swaphead was called in between , which a member, chris from our team acidentally created to change Yoda to Death Vader. But since we do not want anyone to change it we assign the variable to final so that the java compiler gives an error ,whenever a change is being made to the yoda.FInal means you can assign only once Hope this was helpful.

Yes, I missed this too, as it does get unclear here. But if you go back in the video and listen at around 1 min he discusses it. So, Chris made a new method that changed the character head (aka he calls it swapHead) and returns the previous one (aka before, which in Pez.java is labeled as original). Then, get.CharacterName() is getting the input string, aka ("Darth Vader") from Example.java. Hope that helps!
