24,063 PointsThe printf method will print out a formatted string. The %s and %n are formatting items where %s will be formatted with the string passed as a parameter after the string (in this case, itβs dispenser.characterName). %n just adds a new line at the end of the string because printf does not add a new line by default the way println does.

16,873 PointsYou got two good answers already, but I just wanted to add, as so often is the case, it'll be extremely helpful to study the course and workshops preceding this one. Java Basics, Getting Loopy, and The Thing about Strings. I encountered the %n (that one got me, too) in the workshop, and googled it. These course are all built on top of one another, so it really pays to start at the beginning to at least scan and see what we don't know. The thing about strings is a very good video with a lot of useful info in a very short amount of time:)
