JTextArea need help in size

Question

Hello everyone. I have a quick question. When my program opens I have the window open to the max by getting the screen size dimension. I also have a text area in the frame that I would like do to the same. Any ideas? I have tried setRow, setCol but the problem is these will vary across computers. I tried textArea.setSize(dimension of screen) but this only accounts for the cols, not rows so it sizes the cols to the max but not the rows.

Gotcha, ok I must be doing something wrong somewhere. Thanks for helping me out, I will post my code. Also, looking back at my code I was not using border layout so this may have been the problem. Can you take a peak though? It may be something else. I would basically like the text area to resize when the window does but always fill up all the space under the menu. If I can get this working I'm almost done since all the functionality works. I left out that code though to shorten this up some, I mainly added the code where I create and add the panel to the frame.
This is the driver, basic creation of the frame
import javax.swing.JFrame;
import java.awt.*;
public class Run {
  public static void main(String args[]) {
    Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    Notepad n = new Notepad();
    n.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    n.setSize(screenSize);
    n.setVisible(true);
}Here is the panel where I store the text area
I also use this class to handle operations on the text area such as reading/writing to disk etc. I left out the functionality code to keep it small and to the point.
public class NotepadFile extends JPanel {
  private JTextArea mainTextArea;
  public NotepadFile( ) {
    setLayout(new FlowLayout()); //default 
    mainTextArea = new JTextArea();
    mainTextArea.setLineWrap(true);
    add(mainTextArea);     
}Finally, here is where I add the panel to the main frame. Again, i'm leaving out the functionality code like event handlers and such.
public class Notepad extends JFrame {
  private NotepadFile nFile;
  private final int fileMenuIndex = 0,
              formatMenuIndex = 1,
              helpMenuIndex = 2;
  public Notepad( ) {
    super("Notepad");
    JMenuBar mainMenuBar;
    JMenu menu[];
    nFile = new NotepadFile();
    mainMenuBar = new JMenuBar();
    setJMenuBar(mainMenuBar);
    menu = new JMenu[menuNames.length];
    for(int i=0;i<menuNames.length;i++) {
      menu[i] = new JMenu(menuNames); //create a menu
menu[i].setMnemonic(menuMnemonic[i]);
//here is where I created menu items but I cut it out here
//continued..
for(int i=0;i<menuNames.length;i++)
mainMenuBar.add(menu[i]); //add menus to menu bar
add(new JScrollPane(nFile));
//here I also tried add(new JScrollPane(nFile), BorderLayout.CENTER); but it didn't work
