I'd like to install java 8 and javafx on ubuntu 18.04.



I installed openjdk-8-jdk, openjfx and openjdk-8-jre via apt but a compilation of hello world app fails since javac is unable to locate javafx.



$ sudo apt install openjdk-8-jdk openjfx openjdk-8-jre
$ javac -version
javac 1.8.0_191
$ cat App.java
import javafx.application.*;
import javafx.stage.*;
import javafx.scene.*;
import javafx.scene.layout.*;

public class App extends Application {
@Override
public void start(Stage primaryStage) {
Pane pane = new Pane();
Scene scene = new Scene(pane, 300, 250);

primaryStage.setTitle("Hello, World!");
primaryStage.setScene(scene);
primaryStage.show();
}

public static void main(String args) {
launch(args);
}
}
$ javac App.java
App.java:1: error: package javafx.application does not exist
import javafx.application.*;
^
App.java:2: error: package javafx.stage does not exist
import javafx.stage.*;
^
App.java:3: error: package javafx.scene does not exist
import javafx.scene.*;
^
App.java:4: error: package javafx.scene.layout does not exist
import javafx.scene.layout.*;
^
App.java:6: error: cannot find symbol
public class App extends Application {
...


I tried to locate javafx as said here but it not there on my system.



$ ls /usr/lib/jvm/java-8-openjdk-amd64/bin/
appletviewer java java-rmi.cgi jhat jrunscript keytool rmic servertool xjc
extcheck javac jcmd jinfo jsadebugd native2ascii rmid tnameserv
idlj javadoc jconsole jjs jstack orbd rmiregistry unpack200
jar javah jdb jmap jstat pack200 schemagen wsgen
jarsigner javap jdeps jps jstatd policytool serialver wsimport



Also it seems like I have 2 versions of java but I installed it only by commands above.



$ ls /usr/lib/jvm/
java-1.8.0-openjdk-amd64 java-8-openjdk-amd64
