JavaFx Label - how to force a new line (line break)

Question

I am trying to write to a JavaFX label. I can write successfully and use wrapping to make sure the text wraps to a new line if it is longer than the label. My issue is I need to add text to the existing text which I can do, but I am unable to make the next text start on a new line.

Any help would be appreciated.

I have been looking for multiline label trick in FXML for some time and many times I visited this post (google displayed this result, a lot of frustration). So I think I will write it here.

I managed to find this code to display multiline:

<Label text="${'number of registered\nreaders'}"/>

But if I define variable

<fx:define>
    <String fx:id="LABEL_01" fx:value="${'number of registered\nreaders'}"/> 
</fx:define>

then I have no idea how to refer to it, I can't use $LABEL_01.

In FXML you can also use this: ''. Then this code works:

<fx:define>
    <String fx:id="LABEL_01" fx:value="number of registered&#xD;readers"/> 
</fx:define>

And you can use LABEL_01 like this:

<Label text="$LABEL_01"/>

regarding `$LABEL_01`, binding expressions dont have variable shorthand, so `${LABEL_01}` will work — Groostav, Oct 09 '19 at 21:53

Just add a newline character:

Label label = new Label();
label.setText("Hello\nWorld");

hmm ... I prefer your earlier answer https://stackoverflow.com/a/22351080/203657 - or maybe I don't understand what the OP really wants to know :) – kleopatra Oct 24 '17 at 10:43
@kleopatra "I am unable to make new text start on a new line": I interpret that to mean that the OP wants a new line at a specific point in the text. – James_D Oct 24 '17 at 11:26
ahh .. yeah, that could well be, my bad :) – kleopatra Oct 24 '17 at 12:19
i was being a dummy using /n not \n – user3325416 Oct 24 '17 at 14:24

You can try something like:

 yourlabel.setText(yourLabel.getText() + System.lineSeparator() + "New String");
