Receiving Email with Java using imap throws connection timed out

I'm trying to create a program with Java that come into my gmail account and prints the sender, subject, and body of unread emails.

Here's the code:

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

public class CheckingMails {

    public static void main(String[] args) {
        Properties props = new Properties();
        props.setProperty("mail.store.protocol", "imaps");
        try {
            Session session = Session.getInstance(props, null);
            Store store = session.getStore();
            store.connect("imap.gmail.com", "[email protected]", "password");
            Folder inbox = store.getFolder("INBOX");
            inbox.open(Folder.READ_ONLY);
            Message msg = inbox.getMessage(inbox.getMessageCount());
            Address[] in = msg.getFrom();
            for (Address address : in) {
                System.out.println("FROM:" + address.toString());
            }
            Multipart mp = (Multipart) msg.getContent();
            BodyPart bp = mp.getBodyPart(0);
            System.out.println("SENT DATE:" + msg.getSentDate());
            System.out.println("SUBJECT:" + msg.getSubject());
            System.out.println("CONTENT:" + bp.getContent());
        } catch (Exception mex) {
            mex.printStackTrace();
        }
    }
}

Here are the errors that appear, I do not understand the reason for these errors.

Anyone knows how I can fix it?

There is nothing wrong with the code. The translated error from italian to english is : connection timed out

Try adding the following properties to your prop object to override the default ones:

props.setProperty("mail.imap.port", "993");
props.setProperty("mail.imap.connectiontimeout", "5000");
props.setProperty("mail.imap.timeout", "5000");

If the error persists, you can use the command telnet imap.gmail.com {port number} in cmd line to check the port connection. The error might be caused by a firewall or networking problems.
