[burnt wigeon]

Are you using IntelliJ Community or Ultimate Edition?

[sonic moth]

idk?

[burnt wigeon]

I think you can use the Maven Archetype option and select "maven-archetype-quickstar (or maven-archetype-fxml) from org.openjfx

[sonic moth]

?

[burnt wigeon]

I think the option is only available in the paid version

[burnt wigeon]

but that should still work in the free one

[sonic moth]

wait why use maven isntead of wtv im trying to use

[burnt wigeon]

On the left side of your first screenshot, there's a Maven archetype option

[burnt wigeon]

Maven is one of the build tools you can use for JavaFX projects

and I would recommend using Maven for JavaFX either way.

and Maven archetypes are basically project tenplates

[sonic moth]

is there a difference?

[burnt wigeon]

difference between what exactly?

[sonic moth]

uHm

huh??

i got javafx?

it spawned out of no where

i was following some yt video from 2 months ago rn about javafx intellj, but decided to listen to u, so i just reset all the settings back to default

and reopened intellj

and ts poppedup

[burnt wigeon]

that looks like IntelliJ Ultimate (the paid version of IntelliJ)

[sonic moth]

i didnt pay nothing gng

[burnt wigeon]

maybe they also changed their licensing or whatever

In the past, at least most of these pptions were exclusive to the paid version

or maybe you activated the free trial

[sonic moth]

i was following some yt video on how to do the javafx templetate but they got to a stage where i couldnt continue witht hem cuz some file type named fxml or something like that wasnt on my screen, so i reset setting

and it popped up

[sonic moth]

doesnt that require me to enter payment details?

also do i go with javafx then?

[burnt wigeon]

no but it only works for a limited amount of time AFAIK

[sonic moth]

hm

[burnt wigeon]

You can

[sonic moth]

how can i check if i got free trial on

[burnt wigeon]

If it uses Maven, that's perfectly fine

[burnt wigeon]

Honestly, I don't know

[sonic moth]

lol

[burnt wigeon]

but if it's a normal Maven project, it will still work with the free version

[burnt wigeon]

I don't even use IntelliJ

[sonic moth]

whats difference between the javafx intellj and the maven 1

[sonic moth]

what u use

[burnt wigeon]

IntelliJ is the IDE i.e. the program you are screenshotting

the thing you write the code in

JavaFX is a UI framework. It adds additional classes that allow building Java applications with GUIs

Maven is a build tool. It allows specifying what libraries (e.g. JavaFX) you are using, where everything is located and a lot of other things. Maven would essentially manage the (Java) project and build it for you.

[burnt wigeon]

I personally use Eclipse instead of IntelliJ

[sonic moth]

should i use it might aswell?

[burnt wigeon]

you can use whatever you prefer

[sonic moth]

whats the difference tho beteeen mavan and javafx im confused still icel

[sonic moth]

is there a difference?

[burnt wigeon]

Those tools are solving different problems

[burnt wigeon]

JavaFX is for building GUIs.
Macen handles (building) Java projects and dependencies.

[sonic moth]

so in mavan i can get javafx to build guis or wat

[burnt wigeon]

There are various differences but both Eclipse and IntelliJ are doing similar things

[burnt wigeon]

Yes, you can use Maven for JavaFX projects

[sonic moth]

in ur opinion do i downlaoded eclipse and get javafx on there and life is fun and ez ig lol?

[burnt wigeon]

You can also use Gradle (an alternative to Maven) for JavaFX

[burnt wigeon]

Both work well. I prefer Eclipse but that doesn't mean it's better for you. It's a matter of your preference.

[sonic moth]

ok eclipse it is 😭

[burnt wigeon]

The Maven setup for JavaFX should be pretty much the same with both Eclipse and IntelliJ

[sonic moth]

can i get javafx on eclipse?

[burnt wigeon]

You can create a Maven project using one of the JavaFX archetypes

[burnt wigeon]

You don't really need a plugin for it (at least not with Maven) but there is one available.

[sonic moth]

ok basically why i am doing javafx for gui cuz im 1st yr cs student

wanting to get an internship this summer

so i am trying to learn java ahead of uni, like faster than uni

to create projects for cv

so ofc i gotta start small, i did a tictactoe game in the console ui of

uh

vscode

now i wanna go into make gui

to make it in a gui

so then i can expand and make other things with the gui yk?

[burnt wigeon]

That's perfectly fine but note that JavaFX is a library that gets complex pretty quickly

[sonic moth]

ok ty

here i will ddownload eclipse

[sonic moth]

https://youtu.be/9XJicRt_FaI?si=-OyY_ziNNIiiQQLs

im watchin ts serious

series*

is this fine

[sonic moth]

damn

eclipse is a bit weird icel

like so many gra white colours

looks old

[burnt wigeon]

probably

[burnt wigeon]

There's also a dark theme if you really want to use that

[burnt wigeon]

Are you using Windows?

if so, that's why

[sonic moth]

no mac

[burnt wigeon]

ok

[sonic moth]

here i will test both ide's and see

i got both open

in intellj

i made new project iwht maven

and for eclipse

uh what to do here

[burnt wigeon]

Did you select the archetype option in IntelliJ?

[burnt wigeon]

press next

[burnt wigeon]

there's a "Maven Archetype" section on the left

[sonic moth]

i see

i dont think that was there before whateer gave me all these options

but i will use it anyhow

nvm it was

[burnt wigeon]

That's where you select the archetype to use. Is there a "javafx-archetype-simple" option?

[burnt wigeon]

you can use the filter/search

[sonic moth]

nope there is not

[burnt wigeon]

or openjfx-archetype-simple

[sonic moth]

no

maybe i need to download the javafx? first

from the site

[burnt wigeon]

that isn't necessary with Maven

[sonic moth]

ok tho it is not there

[burnt wigeon]

there should be an "org.openjdk:javafx-archetype-sinple"

bit you might need to change the catalog to Maven Central or similar

in the dropdown at the top

[sonic moth]

i clciked smth and somehow it brought 100 more thing

idek

[severe sky]

They have been merged now btw. https://blog.jetbrains.com/idea/2025/12/intellij-idea-unified-release/

[sonic moth]

so wait, javafx and all the things is free?

[burnt wigeon]

yeah ik but one is still effectively using one or the other depending on whether they have a licence or not

[sonic moth]

@severe sky like ts is for everyone not free trail?

[severe sky]

JavaFX was always free.

[burnt wigeon]

JavaFX is free, yes. But the dedicated IntelliJ support for it might not be.

[sonic moth]

i meant like being in the side bar to choose

[sonic moth]

here dan1st

[burnt wigeon]

you'd select one of the ones with "org.openjfx" on the left side as these are official

[sonic moth]

anyone of them?

[burnt wigeon]

Do you want to use FXML/scene builder?

[sonic moth]

i got two of theml

fxml or simple

[burnt wigeon]

Do you want to use Scene builder?

[sonic moth]

idk what that is i just started lol

[burnt wigeon]

I guess just atart with the -simple one

[sonic moth]

cuz im just tryina elarn guis

[burnt wigeon]

Scene builder gives you a GUI for designing GUIs that can more or less be loaded with JavaFX

[sonic moth]

what?

[burnt wigeon]

Now you can enter a group and artifact id.

The artifact ID is more or less the project name

the group id should basically identify you

or whoever owns the project

[sonic moth]

so enter wtv name?

for both

artifical and group

[burnt wigeon]

normally you would use reverse domain name notation for the group id (or something like io.github.yourgithubusername) but just using your username is probably fine fir now as well

for the group id

just don't include any weird characters or spaces

[sonic moth]

ok

i dont get it lol but i will just right deendefined ig

anything else or that page

[sonic moth]

like properaties or wtv

[burnt wigeon]

you can change the JavaFX version in the properties to 25 or similar if you want to

but you don't have to

[sonic moth]

does it make a difference

ok done

[burnt wigeon]

then you can click on finish

[sonic moth]

i did

this was the last thing it gave

package: deendefined.Testing

but nothing oepned

[burnt wigeon]

Can you show a screenshot?

[burnt wigeon]

in the console, you need to confirm it by typing Y

[sonic moth]

ok down

done*

1 thing how do i fix the colours

it looks so... old.

[burnt wigeon]

If you want to change what Eclipse looks like, you can do that in Window > Preferences > General > Appearance

[sonic moth]

uuhm

[burnt wigeon]

ok apparently there is no Window > Preferences on macOS

if you press Cmd+3, something should pop up

there, you can enter "Appearence"

or "Color"

[sonic moth]

HUH

its already dark

why is it gray not black then

[burnt wigeon]

that dark gray is the dark theme

It is possible to add custom colors for people that really want to customize it though

[sonic moth]

yikes so i cant black

okay let me setup the other IDE

sry for taking so long btw

ty for ur help

whats after this

[burnt wigeon]

set catalog to a different option (maybe Maven Central)

and select the javafx-archetype-simple (the same one as before)

[sonic moth]

simple for now?

[burnt wigeon]

yes

[burnt wigeon]

there's also the darkest dark theme as an alternative but that's a third party plugin that broke things in the past

[sonic moth]

javafx vers 25?

[burnt wigeon]

yes

[sonic moth]

also the default jdk it gave?

[burnt wigeon]

probably

[sonic moth]

ok now what

[burnt wigeon]

Screenshot?

[burnt wigeon]

That should be a working JavaFX project (the same that you also created with Eclipse)

[sonic moth]

ok i will now watch the tutorial above

where do i code

in what file

oh in src

nvm

im blind

[burnt wigeon]

the relevant files are in src/main/java, yes

[sonic moth]

weird

it's using "var"

[brave night]

public class App extends Application {

    @Override
    public void start(Stage stage) {
        var javaVersion = SystemInfo.javaVersion();
        var javafxVersion = SystemInfo.javafxVersion();

        var label = new Label("Hello, JavaFX " + javafxVersion + ", running on Java " + javaVersion + ".");
        var scene = new Scene(new StackPane(label), 640, 480);
        stage.setScene(scene);
        stage.show();
    }

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

} ```

This message has been formatted automatically. You can disable this using /preferences.

[sonic moth]

confused why they used var

[burnt wigeon]

Because they decided to do it that way? Both options work

[sonic moth]

i mean isnt var old?

[burnt wigeon]

In JavaScript, yes

In Java, no

[sonic moth]

oh lol

so for me the layout is different than the ones using javafx?

[burnt wigeon]

var is a bit of a different concept in Java than in JS

[sonic moth]

in terms of file structure

[sonic moth]

is a nonchangeable variable?

[burnt wigeon]

no

if you don't want it to be modifiable, you need final

e.g. final var

or final Scene scene = new Scene(...);

[sonic moth]

oh var is jut creatin variable without definign the type

until the data is put in

[sonic moth]

WARNING: A restricted method in java.lang.System has been called

does this matter

[burnt wigeon]

not for now

[sonic moth]

in the vid he has difference code than i do

is that cuz of uh maven

they got a file

named application.css?

I don't know what code they started with (if you are using a different template/archetype, the code will be different).

JavaFX supports CSS

If you use the javafx-archetype-fxml archetype, I think you'd start out with some other things including a CSS file

[sonic moth]

Ok I see

I have a small question tho

Basically I am doing this gui stuff just to make half decent projects for cv

Cuz rn I am a 1sy yr cs student

And I want to ger an internship this summer

So ykwim?

I was told by someone this gui wont really benefit me and I should go and do some project using REST Api servers?

What do you think

[hot shell]

holy moly

250 messages

[hot shell]

rest api sounds decent

[sonic moth]

tbh no point changing every second

ima just continue learning guis for now

and uh

do some projects

then do smth els

ykwim

[hot shell]

yikwum

[sonic moth]

lol

[burnt wigeon]

You should do projects that motivate you. If GUIs are interesting for you, do that.

But JavaFX is a pretty complicated topic

[sonic moth]

Ok I after I finish this tic tac toe and calc project in gui

Any recommendations for proper projects

[burnt wigeon]

whatever is interesting to you

[sonic moth]

Create a road crossing game

[sonic moth]

Is dis possible.

Using Java gui

[burnt wigeon]

yes

[sonic moth]

would yk why the url for imageview isnt working

ik i can just put path link

but i want to understand why it is not connecting

[sonic moth]

@severe sky

i was told to stop learning javafx scenebuilder

as its not sued anymore?

[severe sky]

I never used JavaFX. No idea.
Regarding the not-found image are you sure it is located correctly? It should be directly in the working directory of your project to be found under this path.

[burnt wigeon]

• The image should be in src/main/resources or src/main/resources/testing
• Try getClass().getResource("deen.png") for the first location or getClass().getClassLoader().getResource("deen.png") for the second location

[burnt wigeon]

What makes you so sure about that?

I just heard about a company deciding to use JavaFX a few days ago. I don't know whether they use scene builder but I'd say it's pretty likely

[sonic moth]

I realised

Even if it is rarely used

It dont matter tbh

Because I am not looking for jobs im looking for an internship

So really any project is fine as along as the project it self is half decent

Correct me if im wrong

[sonic moth]

I made a resource and imsgd file dw

Idk what it didn't create by itself when I created the project

Okay also now I was following the guide and they went to dxml (scene builder) so I made a new projecr and I used javafx-fxml and I dow loaded scene builder and I linked it to my intellJ

Now when I continued the guide their code inside of the files that got auto created from creating the project is like completely different to mine

Same for their folder layout and file lay out

[burnt wigeon]

sounds good

[sonic moth]

No LOL

What i was saying is

My code is completely different same for mt folder and file layout then the toturoial

I'm confused cuz there is no way in 5 yrs it changed mt code and layout thar much

[sonic moth]

this is the turoials

this is mine

they said to go into the fxml file and i did its compeltely diffrent but when i went into the App file the code is like 70% similar?, and also why is the folder and file layout soo different?

[burnt wigeon]

It seems like the tutorial isn't using a Maven project

JavaFX projects without Maven are a big pain for anyone involved

All your Java classes go into src/main/java

All your other resource files (images, FXML files, etc) go into src/main/resources

and whether your package is called sample or testing doesn't really make a difference

[sonic moth]

i realised smth else

he is main

i thought he was in fxml lOL

idk why he said go to fxml

here is my main

i think i will delete my code

and copy his

so i can follow alone

cuz there isnt really anything i can do yk

no new tutorials online

[burnt wigeon]

You can still use the Maven project structure (with src/main/java etc) if you want to

[sonic moth]

so i just change everything to how he has it you mean

or continue my structure

[burnt wigeon]

I would personally keep the structure with src/main/java etc

[sonic moth]

and just change the code in app to his code

[sonic moth]

?

[burnt wigeon]

sure
