How to set the size of a class that extends JDialog

Question

Hi,
I was trying to set the size of my dialog window to be 600 by 600, but couldn't change it. Here is my code:
public class alii extends JDialog {
/** Creates new form alii */
public alii(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
private void initComponents() {
Container contentPane = getContentPane();
addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent evt) {
closeDialog(evt);
pack();
public static void main(String args[]) {
JFrame frame = new JFrame();
alii a = new alii(new javax.swing.JFrame(), true);
frame.setSize(600,500);
frame.setLocation(200,200);
frame.setVisible(true);}}
Please help me with this and explain to me what is the problem and what needs to be changed.
Cheers

Hi,
The code you sent me doesn't work, and the code I posted wasn't a complete, but there is the complete one. You can see now what the code does.

You were right that I am know to this, but getting there slowly and thanks for your help.
