Toggle icons in runtime   In addition to the responses here  I found that once you have assigned an Icon to your application by the first time you cannot toggle it by just adding a new icon to your stage  this would be helpful if you need to toggle the icon of your app from on off enabled disabled     To set a new icon during run time use the getIcons   remove 0  before trying to add a new icon  where 0 is the index of the icon you want to override like is shown here      Setting icon by first time  You can do this on your start method   stage getIcons   add new Image getClass   getResourceAsStream  enabled png         Overriding app icon with a new status  This can be in another method  stage getIcons   remove 0   stage getIcons   add new Image getClass   getResourceAsStream  disabled png        To access the stage from other methods or classes you can create a new static field for stage in you main class so can access it from out of the start   method by encapsulating in on a static method that you can access from anywhere in your app    public class MainApp extends Application       private static Stage stage      public static Stage getStage     return stage          Override public void start Stage primaryStage            stage   primaryStage         stage getIcons   add new Image getClass   getResourceAsStream  enabled png               public class AnotherClass       public void setStageTitle String newTitle            MainApp getStage   setTitle newTitle           MainApp getStage   getIcons   remove 0           MainApp getStage   getIcons   add new Image getClass   getResourceAsStream  disabled png

If you run the jar file  the code specified by Michael Berry will change the icon in the title bar and in the taskbar  Shortcut icon cannot be changed   If you run a native program compiled with com zenjava  You must add a link to the program icon    lt plugin gt       lt groupId gt com zenjava lt  groupId gt       lt artifactId gt javafx-maven-plugin lt  artifactId gt       lt version gt 8 8 3 lt  version gt       lt configuration gt                   lt bundleArguments gt               lt icon gt   project basedir  src main resources images filename ico lt  icon gt           lt  bundleArguments gt       lt  configuration gt   lt  plugin gt    This will add an icon to the shortcut and taskbar

Assuming your stage is  stage  and the file is on the filesystem   stage getIcons   add new Image  file icon png       As per the comment below  if it s wrapped in a containing jar you ll need to use the following approach instead   stage getIcons   add new Image  lt yourclassname gt  class getResourceAsStream  icon png

stage getIcons   add new Image  lt yourclassname gt  class getResourceAsStream   icon png         You can add more than one icon with different sizes using this method The images should be different sizes of the same image and the best size will be chosen  eg  16x16  32 32

If you have have a images folder and the icon is saved in that use this   stage getIcons   add new Image  lt yourclassname gt  class getResourceAsStream   images comparison png        and if you are directly using it from your package which is not a good practice use this  stage getIcons   add new Image  lt yourclassname gt  class getResourceAsStream  comparison png        and if you have a folder structure and you have your icon inside that use  stage getIcons   add new Image  lt yourclassname gt  class getResourceAsStream     images comparison png
