Problems on JavaFx：The image doesn't show

Question

I inserted an image object in my code. The program compiles and runs, but the image doesn't show.

Here is my code

package JavaFX;

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

import java.io.File;

public class ShowImage extends Application {
    public void start(Stage primaryStage){
        Pane pane = new HBox(10);
        pane.setPadding(new Insets(5,5,5,5));
        Image image = new Image(new File("image/v2-7c37a26d9dd77abf6de2ca9ca3fc7ae0_720w.jpg").toURI().toString());//remember this must be an url address,
        // file should be converted to url

        pane.getChildren().add(new ImageView(image));

        ImageView imageView2 = new ImageView(image);
        imageView2.setFitHeight(100);
        imageView2.setFitWidth(100);
        pane.getChildren().add(imageView2);

        ImageView imageView3 = new ImageView(image);
        imageView3.setRotate(90);
        pane.getChildren().add(imageView3);

        Scene scene = new Scene(pane);
        primaryStage.setTitle("ShowImage");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

The compiler doesn't show any errors or warnings.

Answer 1

Your code generally works, so the problem is most likely an issue with the image.

You should inspect the errorProperty and exceptionProperty, for example...

if (image.errorProperty().getValue()) {
    image.exceptionProperty().getValue().printStackTrace();
}

Runnable example...

import java.io.File;
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

public class App extends Application {

    @Override
    public void start(Stage stage) {
        Pane pane = new HBox(10);
        pane.setPadding(new Insets(5, 5, 5, 5));

        Image image = new Image(new File("image/v2-7c37a26d9dd77abf6de2ca9ca3fc7ae0_720w.jpg").toURI().toString());//remember this must be an url address,
        if (image.errorProperty().getValue()) {
            image.exceptionProperty().getValue().printStackTrace();
        }

        pane.getChildren().add(new ImageView(image));

        ImageView imageView2 = new ImageView(image);
        imageView2.setFitHeight(100);
        imageView2.setFitWidth(100);
        pane.getChildren().add(imageView2);

        ImageView imageView3 = new ImageView(image);
        imageView3.setRotate(90);
        pane.getChildren().add(imageView3);

        Scene scene = new Scene(pane);
        stage.setScene(scene);
        stage.sizeToScene();
        stage.show();
    }

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