JavaFX not accepting the correct URL for Image object

Question

While attempting to mess around with JavaFX and its basic functions on java 1.8 I kept running into the issue that my Image objects would not accept the URL for a png file contained within my src folder. The icon image object gave me trouble at first but when I copied the file name via the "Copy Path/Reference..." option it worked. This was not the case for the coinImage object where no matter how I format the image URL it will not accept it. To clarify, my files are named "icon.png" and "coin.png" and they are placed in the src folder. I have tried the following formats:

Image coinImage = new Image("coin.png");
Image coinImage = new Image("/coin.png");
Image coinImage = new Image("file:coin.png");
Image coinImage = new Image("file:/coin.png");

Below is the code which most relates to the problem to reduce on the size of this question:

public class MainStage extends Application {
    public void start(Stage stage) throws Exception{
        Group root = new Group();
        Scene scene = new Scene(root,1000,1000,Color.LIGHTSKYBLUE);
        Image icon = new Image("icon.png");

        Image coinImage = new Image("coin.png");
        ImageView imageView = new ImageView(coinImage);
        imageView.setX(400);
        imageView.setY(500);

        root.getChildren().add(imageView);
        stage.getIcons().add(icon);
        stage.setTitle("Test");
        stage.setScene(scene);
        stage.show();
    }

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

Here are all of my imports as well but I do not think they are the issue here:

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.scene.shape.Line;
import javafx.scene.shape.Polygon;
import javafx.scene.shape.Rectangle;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;

If any additional information is needed I should be able to provide it. Thanks.

Refer to the [Eden resource guide](https://edencoding.com/where-to-put-resource-files-in-javafx/). Check the binary output of your build and ensure that the resource is actually in the location you are looking for it. Also see: [How do I determine the correct path for FXML files, CSS files, Images, and other resources needed by my JavaFX Application?](https://stackoverflow.com/questions/61531317/how-do-i-determine-the-correct-path-for-fxml-files-css-files-images-and-other), examples are in the [Image javadoc](https://openjfx.io/javadoc/17/javafx.graphics/javafx/scene/image/Image.html). — jewelsea, Feb 05 '22 at 10:17
don't _mess around_ with random parameters, instead work through a decent tutorial on the basics (at the very least study the api doc of related classes throroughly - they might be a bit on the dense side, but digging into every single word/class you don't know yet will help :) — kleopatra, Feb 05 '22 at 11:35

It is recommended to keep images and resources in a dedicated assets folder.

You need to have the assets folder in your classpath.

Set the assets directory as a resource directory and then create a javafx Image from location: "/coinImage.png":

If you are using IntelliJ To set folder as resource directory follow this guide

This issue is coming from the fact that Java will search for your image file in the bin directory. You should put your image in the bin directory.

I added a small print in your code that can help for debugging

System.out.println("GET  PATH"+this.getClass().getClassLoader().getResource("").getPath());

The output that i got

GET PATH /D:/Nabil-local/eclipse-workspace/Stackoverflow/bin/

I think there is another way to specify a folder
