Just to be sure... you want to change alert's window icon or icon displayed next to message? – Wortig Mar 28 '21 at 12:33

This should answer your question altough it is for javafx version 8. https://stackoverflow.com/questions/27976345/how-do-you-set-the-icon-of-a-dialog-control-java-fx-java-8 – Wortig Mar 28 '21 at 12:42

please don't add tags that are not needed - it's nothing version specific :) – kleopatra Mar 28 '21 at 13:06

like this?
@Override
public void start(Stage stage) {
Alert alert = new Alert(Alert.AlertType.ERROR);
alert.setTitle("Alert Test");
alert.setHeaderText("Hello, world!");
ImageView icon = new ImageView(new Image(String.valueOf(this.getClass().getResource("img/close-on.png"))));
icon.setFitHeight(48);
icon.setFitWidth(48);
alert.getDialogPane().setGraphic(icon);
alert.show();
}
