NetBeans cannot run this program:

Code:

---

import java.awt.*;
import javax.swing.*;

// create a simple GUI window

public class TopLevelWindow {

    private static void createWindow() {
        // cerate and set up the window
        JFrame frame = new JFrame("Simple GUI");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
       
        JLabel textLabel = new JLabel("Testing Java Application",SwingConstants.CENTER);
        textLabel.setPreferredSize(new Dimension(300, 100));
        frame.getContentPane().add(textLabel, BorderLayout.CENTER);
       
        // Display the window
        frame.setLocationRelativeTo(null);
        frame.pack();
        frame.setVisible(true);

    }
   
    public static void main(String[] args) {

I've moved this thread to the Swing forum.

You don't have anything in your main method. What do you expect to happen?

With this program I want to make a window like that: Attachment 4204

Can u tell me what can i change in this code?

You need to call the method you've created in your main method. Sorry but this suggests that you've got the cart before the horse here. You need to learn basic Java before trying GUI stuff, at least the rudiments like creating and calling methods and such. I suggest that you start here: Trail: Learning the Java Language (The Java™ Tutorials)

but can u tell me what can I add in this program.(I am a beginner in java and I cannot guess what are u talking about :) )

You're not expected to guess. Go through the tutorials linked by Fubarable and learn.
