Send Email in Java Using SMTP Example

Below is the Java program to send email.

Make sure to change the host name, user name, password and port number according to your email provider.

package com;

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

public class SendMail {
	public static void main(String[] args) {
		//change these according to you
		String HOST_NAME="mail.thejavaprogrammer.com";
		final String USER_NAME="contact@thejavaprogrammer.com";
		final String PASSWORD="tjp123";
		String TO="sareneeru420@gmail.com";
		
		//get session object
		Properties props = new Properties();
		props.put("mail.smtp.host",HOST_NAME);
		props.put("mail.smtp.auth", "true");
		props.put("mail.smtp.port", "587");
		
		Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
			protected PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication(USER_NAME,PASSWORD);
			}
		});
		
		try {
			//compose message
			MimeMessage message = new MimeMessage(session);
			message.setFrom(new InternetAddress(USER_NAME));
			message.addRecipient(Message.RecipientType.TO,new InternetAddress(TO));
			message.setSubject("Java Send Mail");
			message.setText("Testing Java Send Mail!!!");
			
			//send message
			Transport.send(message);
			
			System.out.println("Message Sent!!!");
		} catch (MessagingException e) {
			e.printStackTrace();
		}
	}
}

If everything goes fine then you will see “Message Sent!!!” in console.

Note: Disable antivirus in your system otherwise it will cause problem in sending mail.
