when I run the application the output is like that:

Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: C:\Users\HP\IdeaProjects\HelloWorldFX\out\production\HelloWorldFX
Caused by: java.lang.module.InvalidModuleDescriptorException: FirstWindow.class found in top-level directory (unnamed package not allowed in module)

I've downloaded and installed the javaFX but still not getting the output

public class FirstWindow extends Application {

    @Override
    public void start(Stage primaryStage)  {

        Scene scene = new Scene(new Button("OK"),300,300);

        primaryStage.setScene(scene);
        primaryStage.setTitle("First Window!!");
        primaryStage.show();

    }

    public static void main (String[] args){
        Application.launch(args);
    }
}

what I was expecting to occur is a window can someone help me fix this problem?

FirstWindow must be in a named package is what the error tells you :-) – kleopatra Mar 30 '19 at 15:43

move it to a named package - you might consider reading up on some java language basics :) – kleopatra Mar 30 '19 at 15:57
