Lesson 15: send email using java mail API

UPDATE:
copas contoh dari tutorials point aja biar gak ada error:
http://www.tutorialspoint.com/javamail_api/javamail_api_gmail_smtp_server.htm
jangan lupa ganti username & password
kalo sampe eror, biasanya harus disable dulu '2-way account protection' (alternate email & sms)

sebenernya cukup simple buat kirim email pake JavaMail API ini
ini ada satu situs yang lumayan populer di kalangan programmer buat nyari tutorial singkat untuk menjalan suatu fungsi programming tertentu:

Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
 
Session session = Session.getDefaultInstance(props,
 new javax.mail.Authenticator() {
  protected PasswordAuthentication getPasswordAuthentication() {
   return new PasswordAuthentication("username","password");
    }
   });
 
  try {
 
   Message message = new MimeMessage(session);
   message.setFrom(new InternetAddress("from@no-spam.com"));
   message.setRecipients(Message.RecipientType.TO,
     InternetAddress.parse("to@no-spam.com"));
   message.setSubject("Testing Subject");
   message.setText("Dear Mail Crawler," +
     "\n\n No spam to my email, please!");
 
   Transport.send(message);
 
   System.out.println("Done");
 
  } catch (MessagingException e) {
   throw new RuntimeException(e);
