what means pd?

Hello Pedro,

"pd" is just the name of the object that Craig created. You could call it pretty much anything you want, for example:

PezDispenser pedro = new PezDispenser("Hulk");

would simply create a new object called pedro which can be used to reference to the methods in your PezDispenser class. It would look something like this, assuming you know how method calls work:

System.out.printf("The Pez character is: %s %n", pedro.getCharacterName()); //getCharacterName is the method from you PezDispenser.java class.

As Craig also said in the video, "pd" might not be the best name to give the object as it could stand for multiple things such as "police department" and might confuse yourself later on or other developers that'll possibly work on your code with you.

I hope this eased it for you just a bit, let me and the others know if it helped you!
