Исключение "Invalid URL or resource not found" при вызове new Image()

Что делать, если при запуске программы происходит исключение в строке

Image icon = new Image("images.png");

(использую intellij IDEA)

package com.example.app;

import javafx.application.Application;

import javafx.fxml.FXMLLoader;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.input.KeyCombination;
import javafx.stage.Stage;
import javafx.scene.paint.Color;
import java.io.IOException;


public class HelloApplication extends Application {
    @Override
    public void start(Stage Primary_stage) throws IOException {
        Group root = new Group();
        Scene scene = new Scene(root,Color.BLUE);
        Primary_stage.setScene(scene);
        Image icon = new Image("images.png");
        Primary_stage.getIcons().add(icon);
        Primary_stage.setTitle("hello");
        Primary_stage.setFullScreen(true);
        Primary_stage.setFullScreenExitHint("Press s to exit");
        Primary_stage.setFullScreenExitKeyCombination(KeyCombination.valueOf("s"));
        Primary_stage.show();
    }

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