So i have this code in which i'm trying to do a scene for my game. I'm really a beginner in a Java and especially JAVAFX world and doing this as a school project (Once again..) and trying to figure out a way to refresh my label.
I've found one URL from stackoverflow, which was a similar issue but didn't work for my problem (or was i too stupid to make it work..) anyways, link is here
This is the part where the problem occurs - i have a text box, from which you have to enter player names. Every time a user inputs player name the label shows how many names have been entered, according to the nimedlist.size() which holds the names inside.
Label mängijate_arv = new Label("Mängijaid on sisestatud: "+nimedlist.size());
// if we press enter, program will read the name
nimiTekst.setOnKeyPressed(new EventHandler<KeyEvent>() {
public void handle(final KeyEvent keyEvent) {
if (keyEvent.getCode() == KeyCode.ENTER) {
if (nimiTekst.getText() != null) {
nimedlist.add(nimiTekst.getText());
nimiTekst.setText(null);
}
}
}
});
startBox.getChildren().addAll(sisestus_mängijad, nimiTekst, mängijate_arv,
startButton2);
This is the whole code:

Sorry about Estonian language, it's compulsory in our school to write in our native language..
