I've got the following code.
public static void main(String[] args)
{
sendMessage("hello");
}
private static void sendMessage(String s) {
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("[email protected]"));
message.setSubject("subject");
message.setText(s);
Transport.send(message);
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
Password and user name are valid. But exception is the only thing I've got:

Two steps authentication is not enabled in my accaunt. What do?
You can turn on the "less secure apps" feature in gmail so that your code will be able to run. you can access that from your google console
Other than that, you might want to update your code how to access the gmail API nowadays for java in here.
