Question: What is Message in JavaMail api?

Answer: After creating session object, create message to send by using Message class. Because of message class is abstract class so we will use subclass javax.mail.internet.MimeMessage.

MimeMessage message = new MimeMessage(session)
// set the content of message by setContent() method
message.setContent(�www.roseindia.net�, "text/plain");

We can also use setText() method to set the content.

Message.setText("www.roseindia.net");

To create subject line of sending message use setSubject() method.
