How to add text to a textArea instead of replacing it

How can I add text to a JTextArea instead of replacing all of it?

I know about setText(String) but other than that I'm a bit lost.

You can use the append method like this:

textArea.append(additionalText);

void append(JTextArea area, String newText){
        area.setText(area.getText() + newText)
}

To insert string at any position you can use the component's Document.

public static void main(String[] args) throws BadLocationException {
    JTextField f = new JTextField("foo bar");
    int offset = 7;
    String str = " baz";
    f.getDocument().insertString(offset, str, SimpleAttributeSet.EMPTY);
    System.out.println(f.getText());
}
