Getting line count of wrapped text in JTextArea

Question

I'm trying to get the line count of wrapped text in a JTextArea, but I see no way to do it other than to write a function for manually determining the line count, which I'm struggling with. I'm trying to get the following code to print out "4 4" on both lines, but it's printing out "1 1" instead. Is there a built-in way to get the actual line count? I'm guessing the JTextArea.getLineCount() function is supposed to count line breaks, which I don't have.
public class SSCCE
     public static void main(String args[])
          String s = "abc def ghi jkl mno pqr stu vwx yz1 234 567 890";
          JFrame f = new JFrame("test");
          JPanel p = new JPanel();
          JTextArea t[] = {cta(s,1,3),cta(s,1,4)};
          p.add(t[0]);
          p.add(t[1]);
          f.setSize(500,500);
          f.add(p);
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          f.setVisible(true);
          try
               Thread.sleep(200);
          catch (InterruptedException e)
               e.printStackTrace();
          System.out.println(t[0].getRows()+" "+t[1].getRows());
          System.out.println(t[0].getLineCount()+" "+t[1].getLineCount());
}

Oh wait, I see. Never mind. I went back there and saw that there were indeed two (last time I checked, I looked for the first one I saw since you didn't give me the full signature), and I got the one for the JTextArea, but I still need Thread.sleep to get the accurate line count.

}Although, it's not working exactly the way I want it to. Is there a way to get this to work before I paint? It works fine after I paint, but I was just wondering.
