A java program to send a mail

Here is java code to send a mail to a mail address.To implements this we use library mail.jar with the jdk.

Program code:-
import java.io.IOException;
import java.util.*;
import javax.mail.*;        //import classes from mail.jar
import javax.activation.*;
import javax.mail.internet.*;

public class javamail {
public static void main(String args[]) throws AddressException, MessagingException, IOException
{
 Properties props=new Properties();
 props.put("mail.transport.protocol","smtp");    // define protocol

 props.put("mail.smtp.host","localhost");           // defile the host address
 props.put("mail.smtp.port","25");                   // define a port address of protocol
 Session mailSession=Session.getInstance(props);
 Message msg=new MimeMessage(mailSession);
 msg.setFrom(new InternetAddress("navin@localhost"));
 msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse
                      ("raj@localhost"));
 msg.setSentDate(new Date());
 msg.setSubject("Test mail");
msg.setText("hello mail");

 msg.writeTo(System.out);    // to write the detail on the consol
  }

}

Here getSession() contain three arguments:-
1. Protocol name.
2. Host address or server address.
3. Port number of the service. Here this service is open on port no. 25.
