mail() - Launch Default Email Program

This section provides a tutorial example on how to use Desktop.mail() method to launch the default email program on the desktop of the operating system.

If you want to launch the default email program on the current desktop of the operating system, you can get the default Desktop object and call its mail() method. Here is a sample program:

 * Copyright (c) All Rights Reserved.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class DesktopSendEmail {
   public static void main(String[] a) {
      try {
		 String address = "";
		 String subject = "Java%20Swing%20Tutorials";
		 String body = "I%20like%20your%20tutorial%20book!";
         URI uri = new URI("mailto:"+address+"?subject="+subject
         Desktop desktop = Desktop.getDesktop();
         if (desktop != null) desktop.mail(uri);
      } catch (Exception e) {

Note that I have encoded the email address, subject and message body in the mailto URI string.

If you run this program, you will see the default email program is started with the given email content. On my Windows 10 computer, I am getting the Outlook app launched.
