FxmlLoader.load() is not working and I have no Idea why. What should I do?-CodePudding

fxmlLoader.load() doesn't work; Error below. There seems to be something about an init method in the error however I have no clue what that is referring to. Windows 10; IntelliJ; SDK 11;

public class HelloApplication extends Application {
    @Override
    public void start(Stage stage) throws IOException {
        FXMLLoader fxmlLoader = new FXMLLoader(HelloApplication.class.getResource("hello-view.fxml"));
            Scene scene = new Scene(fxmlLoader.load()); //This is line 21
            stage.setTitle("String Checker");
            stage.setScene(scene);
            stage.show();
    }

    public static void main(String[] args){
//        HelloController.readFile();
        launch();
    }

    @Override
    public void stop() throws Exception {
        super.stop();
    }
}

CodePudding user response：

The problem is in the stack trace you posted.

Caused by: java.lang.NoSuchMethodException: com.stringchecker.stringchecker.HelloController.<init>()

HelloController needs a default parameterless constructor.
