So I have a JComboBox, which contains recipe names. I want, when the recipe name is changed, for the label that is an icon of the rating (1 to 5) stars, based on my recipe object, to change as well.
My code seems like it should work perfect but it doesn't. Any help please?

}Here is the code of my recipe class just in case you need to look at it. All my main class does is it creates a new instance of my gui class, that's it.

// These are the main objects that my system will implement.

// Will use an ArrayList because of their functionality.
private ArrayList<String> ingredients = new ArrayList<String>();
// Another ArrayList will be used to contain each direction for making that recipe.
private ArrayList<String> directions = new ArrayList<String>();
// A String of notes for the recipe.
// Things you should know that might not directly affect its outcome.
private String notes = "";
// Three Strings for the filename of each picture for the recipe.
// A beginning picture of the ingredients, middle of the process, and finished recipe.
// This will be optional.
private String picFile1 = "";
private String picFile2 = "";
private String picFile3 = "";
// Difficulty rating as an integer.

// Time it takes to prepare the entire dish from beginning to end.
// Usually an estimate.
// Using a String for this because it should be in HH:MM format.

// How many people does it serve on average?
