 In the previous parts of the tutorial, you created a two-screen user interface. But it is still static, and when you click the buttons, nothing happens yet. The purpose of the +++<abbr title="Graphical User Interface">GUI</abbr>+++ is to communicate with your Java classes: Your game needs to know what the users clicked, which settings they chose, which values they entered into a field, etc. Similarly, the user needs to know what the currently game state is (score, health, etc).
