[FIXED] Appending text into TextArea

Issue

I'm trying to create a TextArea,

@FXML 
private TextArea ta;

and what I'm trying to get :

for (int i=1; i<=5; i++) {
    ta.setText("    Field " + i + "\n");
}

but it only show the last line : Field 5.
Can anyone help. Thanks in advance.

Solution

When you call setText( "..."), you replace the text which is already there. So either construct your String before setting it, or append it. Try this:

String text="";
for (int i=1;i<=5;i++) {
    text = text + "    Field "+i+"\n";
}
ta.setText(text);

Note: You'll probably get better performance and it's considered "good practice" to use a "StringBuilder" instead of a String to build String like this. But this should help you understand what's the problem, without making it overly complicated.
