folder=store.getFolder("INBOX");

folder.open(Folder.READ_ONLY);

Message[] message=folder.getMessages();

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

System.out.println("------------ Message " + (i + 1) + " ------------");

System.out.println("SentDate : " + message[i].getSentDate());
System.out.println("From : " + message[i].getFrom()[0]);
System.out.println("Subject : " + message[i].getSubject());
System.out.print("Message : ");

InputStream stream = message[i].getInputStream();
while (stream.available() != 0)
{
System.out.print((char) stream.read());
}
System.out.println();

Example For Sending Email:


package p1;

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

public class MailSender
{
final String senderEmailID = "Your Email ID For gmail";
final String senderPassword = "password";
final String emailSMTPserver = "smtp.gmail.com";
final String emailServerPort = "465";

String receiverEmailID = null;
String emailSubject = null;
String emailBody = null;

public MailSender(String receiverEmailID, String emailSubject, String emailBody)
{
this.receiverEmailID=receiverEmailID;
this.emailSubject=emailSubject;
this.emailBody=emailBody;


Properties props = new Properties();
props.put("mail.smtp.user",senderEmailID);
props.put("mail.smtp.host", emailSMTPserver);
props.put("mail.smtp.port", emailServerPort);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
// props.put("mail.smtp.debug", "true");
props.put("mail.smtp.socketFactory.port", emailServerPort);
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");

SecurityManager security = System.getSecurityManager();

try
{
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
// session.setDebug(true);

MimeMessage msg = new MimeMessage(session);
msg.setText(emailBody);
msg.setSubject(emailSubject);
msg.setFrom(new InternetAddress(senderEmailID));
msg.addRecipient(Message.RecipientType.TO,
new InternetAddress(receiverEmailID));
Transport.send(msg);
}
catch (Exception mex)
{
mex.printStackTrace();
}


}
public class SMTPAuthenticator extends javax.mail.Authenticator
{
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(senderEmailID, senderPassword);
}
}

public static void main(String[] args)
{

MailSender mailSender=new MailSender("Receiver Email ID","Email Subjectl","Email Body");
}
