Java 17 mail api

Java 17 Mail API!

The Java Mail API is a set of classes and interfaces that provide a way to send and receive email messages in Java applications. The API is part of the Java Standard Edition (SE) and is included in the Java Development Kit (JDK).

Here's an overview of the Java 17 Mail API:

Key Features:

  1. SMTP and POP3 support: The Java Mail API provides support for sending and receiving email messages using the Simple Mail Transfer Protocol (SMTP) and Post Office Protocol version 3 (POP3).
  2. MIME support: The API supports the Multipurpose Internet Mail Extensions (MIME) standard, which allows for the transmission of multimedia content in email messages.
  3. Session and Store objects: The API provides two main objects: Session and Store. The Session object represents a connection to a mail server, while the Store object represents a mail store (e.g., a mailbox).
  4. Message objects: The API provides Message objects, which represent individual email messages. You can create, send, and receive messages using these objects.
  5. Address objects: The API provides Address objects, which represent email addresses.

Java 17 Mail API Classes:

Here are some of the key classes in the Java 17 Mail API:

  1. javax.mail.Session: Represents a connection to a mail server.
  2. javax.mail.Store: Represents a mail store (e.g., a mailbox).
  3. javax.mail.Message: Represents an individual email message.
  4. javax.mail.internet.MimeMessage: A subclass of Message that supports MIME.
  5. javax.mail.internet.MimeBodyPart: A subclass of BodyPart that supports MIME.
  6. javax.mail.internet.InternetAddress: Represents an email address.
  7. javax.mail.internet.AddressException: Thrown when an email address is invalid.

Example Code:

Here's a simple example of sending an email using the Java Mail API:

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SendEmail {
    public static void main(String[] args) {
        // Create a session
        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.example.com");
        props.put("mail.smtp.port", 587);
        Session session = Session.getInstance(props);

        // Create a message
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[email protected]"));
        message.setRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
        message.setSubject("Hello, World!");
        message.setText("This is a test email.");

        // Send the message
        Transport.send(message);
    }
}

This code creates a session, creates a message, sets the from and to addresses, sets the subject and text, and sends the message using the Transport.send() method.

Conclusion:

The Java 17 Mail API provides a powerful and flexible way to send and receive email messages in Java applications. With its support for SMTP, POP3, MIME, and more, it's a great tool for building email-enabled applications.
