ImageExample.java

import javafx.application.Application; 
import javafx.scene.Group; 
import javafx.scene.Scene; 
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;  
import javafx.stage.Stage;  

public class ImageExample extends Application {  
   @Override 
   public void start(Stage stage) throws java.io.FileNotFoundException {         
   
      Image image = new Image(new java.io.FileInputStream("javanetar.jpg"));  
   
      ImageView imageView = new ImageView(image);      
      
      Group root = new Group(imageView);        
      Scene scene = new Scene(root, 600, 500);  
      
      stage.setTitle("Welcome to www.java.net.ar !");  
      stage.setMaximized(true);      
      stage.setScene(scene);     
      stage.show(); 
   }  
   public static void main(String args[]) { 
      launch(args); 
   } 
}

This use JavaFX 11. See https://openjfx.io/ for more info:

You need to set JAVAFX, JAVAFX_MODS, JAVA_HOME and change the path where your java environment is. For example:

export JAVAFX=/opt/openjfx-11.0.2_linux-x64_bin-sdk/javafx-sdk-11.0.2/lib/
export JAVAFX_MODS=/opt/openjfx-11.0.2_linux-x64_bin-jmods/javafx-jmods-11.0.2/
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

To compile:
/usr/lib/jvm/java-11-openjdk-amd64/bin/java --module-path $JAVAFX_MODS --add-modules javafx.controls ImageExample

To run:
/usr/lib/jvm/java-11-openjdk-amd64/bin/java --module-path $JAVAFX --add-modules javafx.controls ImageExample
