Fastest way to create a Java message dialog (swing/awt/other)?

Question

I\'m creating a Java application that will do some processing then needs to display a message to give the user feedback.

However, it appears to be incredibly slow -

Answer 1

I would use a JOptionPane to show the message. Here's a simple example:

import javax.swing.*;

public class OptionDemo {
    public static void main(String[] args) throws Exception {
        JOptionPane.showMessageDialog(null, "Hello World");
    }
}

I'm afraid I can't explain the delay you're experiencing though. On my system, your code snippet runs in 500 milliseconds.
