Sending Emails from Java using Gmail, Yahoo, or Hotmail

Introduction:

Sending emails from Java applications can be essential for various purposes, including notifications, order confirmations, and customer outreach. This article explores the process of sending emails through Java using popular email providers such as Gmail, Yahoo, and Hotmail.

Requirements:

To begin, you will need:

• JavaMail API (available from Maven Central)
• SMTP (Simple Mail Transfer Protocol) credentials for Gmail, Yahoo, or Hotmail

Using Gmail:

The following Java code snippet demonstrates how to send an email using Gmail:

import javax.mail.*;
import javax.mail.internet.*;

public class EmailSender {

    public static void main(String[] args) {
        String from = "myUserName@gmail.com";
        String password = "myPassword";
        String recipient = "recipient@example.com";
        String subject = "Java Email";
        String body = "This is a test email sent from Java.";

        try {
            // Set up mail properties
            Properties props = new Properties();
            props.put("mail.smtp.host", "smtp.gmail.com");
            props.put("mail.smtp.port", "587");
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.starttls.enable", "true");

            // Create the mail session
            Session session = Session.getDefaultInstance(props, null);

            // Create the email message
            MimeMessage message = new MimeMessage(session);
            InternetAddress fromAddress = new InternetAddress(from);
            InternetAddress toAddress = new InternetAddress(recipient);
            message.setFrom(fromAddress);
            message.setRecipient(Message.RecipientType.TO, toAddress);
            message.setSubject(subject);
            message.setText(body);

            // Send the email
            Transport transport = session.getTransport("smtp");
            transport.connect("smtp.gmail.com", from, password);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();

            System.out.println("Email sent successfully!");
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}

Using Yahoo or Hotmail:

The general process for sending emails using Yahoo or Hotmail is similar to that of Gmail. However, there may be slight variations in the SMTP server address and configuration.
