Sending Email using JAVA

Sending email in java is very simple task, as you don’t have to write as much code.  Here I am going to write a code example that send email using JavaMail API via Gmail SMTP server.

In order to run this example you will need to import Mail.jar as dependency library.

import javax.mail.Message;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

import java.util.Properties;

import java.util.Date;

public class MailUtil

{

      

    public static void main(String [] args)

    {

       // Set recipient email address here

       String rec[]= {"abc@gmail.com"};

       try {

                    

           sendMail("Sample Test Email", "This is Message Body...", rec);

       }

       catch (Exception e)

       {

           e.printStackTrace();

       }

    }

      

    public static void sendMail(String subject, String message,

                     String [] recipients) throws Exception

    {

       try

       {

                    

              boolean debug = false;

              Properties props = new Properties();

              // Set the host SMTP address

              props.put("mail.smtp.starttls.enable", "true");

              props.put("mail.smtp.host", "smtp.gmail.com");

              props.put("mail.smtp.port", "587");

              // create some properties and get the default Session

              Session session = Session.getDefaultInstance(props, null);

              session.setDebug(debug);

              // create a message

              Message msg = new MimeMessage(session);

                    

              // Set Sender email address here

              InternetAddress addressFrom = new InternetAddress("xyz@gmail.com");

              msg.setFrom(addressFrom);

                    

              InternetAddress [] addressTo = new InternetAddress [recipients.length];

              for ( int i = 0 ; i < recipients.length ; i++ )

              {

                  addressTo[i] = new InternetAddress(recipients[i]);

              }

              msg.setRecipients(Message.RecipientType.TO, addressTo);

                    

              // Setting the Subject and Content Type

              msg.setSubject(subject + "  " + new Date());

              msg.setContent("\n" + message, "text/plain");

              Transport.send(msg);

                    

              System.out.println("Message has been sent successfully...");

              System.out.println("Please check your inbox...");

                    

          }

          catch (Exception e)

          {

             e.printStackTrace();

          }

    }

}
