JavaFX ImageviewReady Examples

A simple JavaFX tutorial through simple snippets.

Example 1: ImageviewReady

Here are the code:

Step 1: Create Project

1. Open your favorite Java IDE.
2. In the menu go to File --> Create New Project.

Step 2: Dependencies

No dependencies are needed for this project.

Step 3: Write Code

Our code will comprise the following java files:

• ImageViewExample.java

1. In your editor or IDE, create a file known as ImageViewExample.java.
2. Then add the following code:

(a). ImageViewExample.java

First, go ahead and add the following imports:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Accordion;
import javafx.scene.control.Label;
import javafx.scene.control.TitledPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

First, go ahead and add the following imports:

import java.io.FileInputStream;
import java.io.FileNotFoundException;

We will need to extend our class using the extend keyword. By doing that our class can make use of inheritance to derive properties and functions defined in the parent class.

public class ImageViewExample extends Application {

Our class will have the following methods:

• void main(String[] args)
• void start(Stage primaryStage)

Every Java Program must have a main method. This is the entry point of all Java applications include JavaFX. Add a main() method and inside it invoke the launch() function.

    public static void main(String[] args) {

Here is the full code:

package com.jenkov.javafx.imageview;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Accordion;
import javafx.scene.control.Label;
import javafx.scene.control.TitledPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

import java.io.FileInputStream;
import java.io.FileNotFoundException;

public class ImageViewExample extends Application {

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

    public void start(Stage primaryStage) {

        FileInputStream input = null;
        try {
            input = new FileInputStream("assets/media/abstract-5719221_640.jpg");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        Image image = new Image(input);
        ImageView imageView = new ImageView(image);

        VBox vBox = new VBox(imageView);
        Scene scene = new Scene(vBox);

        primaryStage.setScene(scene);

        primaryStage.show();
    }
}
