Create a message dialog box with different options

import java.awt.Component;
import java.awt.FlowLayout;
import java.awt.HeadlessException;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class Main extends JFrame {
  public Main() throws HeadlessException {
    setSize(200, 200);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JButton button1 = new JButton("Message dialog");
    button1.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        JOptionPane.showMessageDialog((Component) e.getSource(), "Thank you!");
      }
    });

    JButton button2 = new JButton("Input dialog");
    button2.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        String text = JOptionPane.showInputDialog((Component) e.getSource(), "What is your name?");
        if (text != null && !text.equals("")) {
          JOptionPane.showMessageDialog((Component) e.getSource(), "Hello " + text);
        }
      }
    });

    JButton button3 = new JButton("Yes no dialog");
    button3.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        int result = JOptionPane.showConfirmDialog((Component) e.getSource(),
            "Close this application?");
        if (result == JOptionPane.YES_OPTION) {
          System.exit(0);
        } else if (result == JOptionPane.NO_OPTION) {
          System.out.println("Do nothing");
        }
      }
    });

    setLayout(new FlowLayout(FlowLayout.CENTER));
    getContentPane().add(button1);
    getContentPane().add(button2);
    getContentPane().add(button3);
  }

  public static void main(String[] args) {
    new Main().setVisible(true);
  }
}

How to show a message dialog box when you click on the button

showMessageDialog():

This method is used to show a message dialog box which contains some text messages. This is being used with two arguments in the program where the first argument is the parent object in which the dialog box opens and another is the message which has to be shown.

code

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

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

  public ShowDialogBox(){
    frame = new JFrame("Show Message Dialog");
    JButton button = new JButton("Click Me");
    button.addActionListener(new MyAction());
    frame.add(button);
    frame.setSize(400, 400);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }

  public class MyAction implements ActionListener{
    public void actionPerformed(ActionEvent e){
      JOptionPane.showMessageDialog(frame,"Roseindia.net");
    }
  }
}
