    Hi try this code here is one button on form when button click's so message box will appear.

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

    public class JavaApplication1{
    JFrame frame;
    public static void main(String[] args){
    JavaApplication1 db = new JavaApplication1();
    }

    public JavaApplication1()
    {
    frame = new JFrame("Form1");
    JButton button = new JButton("Click here for message box");
    button.addActionListener(new Button_Click());
    frame.add(button);
    frame.setSize(300, 300);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public class Button_Click implements ActionListener
    {
    public void actionPerformed(ActionEvent e)
    {
    JOptionPane.showMessageDialog(frame,"Hi, Type your message here");
    }
    }
    }

Howdy, Stranger!
