    String to = "[e-mail]";

    String from = "[e-mail]";
    final String username = "send.address";
    final String password = "sendpassword";
    String host = "smtp.gmail.com";
    Properties pro = new Properties();
    pro.put("mail.smtp.host",host);
    pro.put("mail.smtp.socketFactory.port","465");
     pro.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
    pro.put("mail.smtp.auth","true");
     pro.put("mail.smtp.port","465");
    Session session = Session.getInstance(pro,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication()
                {
                    return new PasswordAuthentication(username,password);
                }
            }

            );
    try 
    {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
        message.setSubject("test mail");
        message.setText("Hello how are you?");
        Transport.send(message);
        JOptionPane.showMessageDialog(null,"Send");
