How to change background color?? U have green progress color, but how can i change the color of progress form behind? U have now white color, how to change it?

[@JLSXMK8]

NOTE: If you're trying to attach a background thread to the progress bar, you can do the following in order to update the progress as the thread is running.
in controller class --> "[progressBar fxID].progressProperty().bind([Task name].progressProperty());"
// This will "bind" your progress bar to a task object.
Then, in your task class --> "this.updateProgress(objectivesCompleted, targetCompletions);"
// The "updateProgress()" method will then update ant progress bars "binded" to the task object.

WARNING GUYSS!! If you are having "Character , is neither a decimal digit number, decimal point, nor "e" notation exponential mark." problem, do not panic.
normally double or int variables uses "." to seperate decimals. When we convert it to String to format it, it turns out to be a "," and this problem annoyed me so much because i couldn't find a solution till now. After 4 fecking hours i come up with this easy solution.
USE this ------> BigDecimal progress = new BigDecimal(String.format("%.2f", 0.0).replace(",", "."));
Simply we replace "," s with "." this.

thank you so much, ran into the same problem, searched for other ways to work with the progress bar, but found your solution now :,)

[@MrAerobitch]

thanks buddie, but it did not work for me 100%

[@Marlon_42]

I coded the hole thing & it works, thank you !

[@haykm81]

instead of BigDecimal, why just not to use - if (progress>1) {progress = 1;} within your IF block (put in line 40) ?

[@MrAerobitch]

it worked, but as far as the last number is 0.99999999999999999 is has to be rounded to 1, it does not work at the end, so better do it this way...at least for me.
if(progress > 0.99) {
progress = 1;
myProgressBar.setProgress(progress);
myLabel.setText(Integer.toString((int)Math.round(progress *100))+" %");
}
if(progress < 1) {
progress += 0.1;
System.out.println(progress);
myProgressBar.setProgress(progress);
myLabel.setText(Integer.toString((int)Math.round(progress *100))+" %");
}

Yo bro , nice video, you finishing C++ and C# ?

[@BroCodez]

yes, in the future. Not sure when exactly tho

[@OmarAli-fw4qm]

you don't need to use BigDecimal, you only need to change the if statement to progress < 0.99 :
if(progress < 0.99){
progress += 0.1;
progressBar.setProgress(progress);
myLabel.setText(Math.round(progress * 100) + "%");
}

[@axelravera5470]

Your video are Amazing bro thanks!
It will be possible to do an management application with good practice methods (SGBD / DAO / View / Presenter / Ihm ) in the futur pls?
You are the best thank's for your job bro!

Peace be upon you brother, can you equate a java project with a full professional postgresql

[@Cadabzy]

What are you using in the start of the video to mess around with the progress bar? Is it an app?

[@kshitijanand3045]

It is a scene builder for javafx(gluon)

[@Cadabzy]

So its called javafx and if that is the case then whats gluon?

[@kshitijanand3045]

@@Cadabzy have you heard of oracle?

Hm... I have the very same code in all classes and the fxml file and im getting this error:
Caused by: java.lang.NumberFormatException: Character , is neither a decimal digit number, decimal point, nor "e" notation exponential mark.
Can anyone help?
