When I create method...

Can you find the bug in this code?

Code:

---

/*

 * and open the template in the editor.
 */

package javaapplication61;
import javax.swing.*;
import java.awt.event.*;
public class ShowDialogBox {
    JFrame frame;

    public static void main(String[] args) {
        ShowDialogBox db = new ShowDialogBox();
        // TODO code application logic here
    }
  [B]  public showDialogBox(){[/B]
        frame = new JFrame("Show Her");
        JButton button = new JButton("Click Me");
        button.addActionListener(new MyAction());
        frame.add(button);
        frame.setSize(200,200);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
    public class MyAction implements ActionListener{
        public void actionPerformed(ActionEvent e){
            JOptionPane.showMessageDialog(frame,"Leann is suckz!");
        }
    }

}

Is there a problem, the way I created "showDialogBox()" method?

It's not a method, it's a constructor, and constructor names have to match class names exactly, including spelling and cApItAlIzAtIoN.

Thanks. Now I have to find tutorials on "constructors". I changed constructor name to be class name. It worked.:)

It's one of the most basic building blocks of the language so studying up on it is a good thing. You're welcome and much luck!

package javaapplication61;

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

public class ShowDialogBox {
        JFrame frame;

        public static void main(String[] args) {
                ShowDialogBox db = new ShowDialogBox();
                // TODO code application logic here
        }

        public ShowDialogBox() {
                frame = new JFrame("Show Her");
                JButton button = new JButton("Click Me");
                button.addActionListener(new ActionListener() {
                        public void actionPerformed(ActionEvent e) {
                                JOptionPane.showMessageDialog(frame, "Leann is suckz!");
                        }
                });
                frame.add(button);
                frame.setSize(200, 200);
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setVisible(true);
