There are times where we need to send an email from our Java Classes and/or web applications build using Java. Java has a mail API which allows you to perform this. All you need is a smtp host url, which would allow you to send an email.

 

// File Name SendEmail.java

import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class SendEmail
{
   public static void main(String [] args)
   {    
      // Recipient's email ID.
      String to = "javagenious.com@gmail.com";

      // Sender's email ID
      String from = "info@javagenious.com";

      // Assuming you are sending email from localhost
      String host = "localhost";

      // Get system properties
      Properties properties = System.getProperties();

      // Setup mail server
      properties.setProperty("something.smtp.host", host);

      // Get the default Session object.
      Session session = Session.getDefaultInstance(properties);

      try{
         // Create a default MimeMessage object.
         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.
         message.setFrom(new InternetAddress(from));

         // Set To: header field of the header.
         message.addRecipient(Message.RecipientType.TO,
                                  new InternetAddress(to));

         // Set Subject: header field
         message.setSubject("SUBJECT GOES HERE!");

         // Now set the actual message
         message.setText("BODY GOES HERE");

         // Send message
         Transport.send(message);
         System.out.println("YOUR EMAIL HAS BEEN SENT !");
      }catch (MessagingException mex) {
         mex.printStackTrace();
      }
   }
}
