I'm trying to automate registration on a website but that site send OTP to the email. so I need to fetch the OTP from the mail and print it to text field.
I am using this code but it's not showing unread message count and the OTP verification mail.
Can anyone help with how can I extract OTP from the email and submit it on the website ?

Java crawler to get all first and third party cookies

But the cookie scanner shows seven. I don't know why my code shows lesser than the CookieMetrix. Can you help me?

JavaDoc for java.util.Set<Cookie> getCookies():
Get all the cookies for the current domain. This is the equivalent of calling "document.cookie" and parsing the result
document.cookie will not return HttpOnly cookies, simply because JavaScript does not allow it.
Also notice that the “CookieMetrix” seems to list cookies from different domains.
Solutions:
To get a listing such as “CookieMetrix” (1+2) you could add a proxy after your browser and sniff the requests.
In case you want to get all cookies for the current domain, including HttpOnly (1), you could try accessing Chrome’s DevTools API directly (afair, it’ll also return HttpOnly cookies)

How can we open a mail with specific subject and specific date in gmail using Java?

I am trying to open a mail in Gmail with a specific subject on a specific date.
I have write down the code where it is fetching all the mails from Gmail in Inbox folder.
How can we get a specific mail content into string format. instead of searching all mails.
how can we search on mails subject name for todays date ?

How do I manipulate arrays created from a match.find?

Here is the code I have:
import java.util.Properties;
import javax.mail.Folder;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Store;
import java.util.List;
import java.util.ArrayList;
import java.util.regex.*;
public class EmailReader {
public static void main(String args[]) {
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
try {
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect ("imap.gmail.com", "email#gmail.com", "password");
System.out.println(store);
Folder inbox = store.getFolder("Inbox");
inbox.open(Folder.READ_ONLY);
Message messages[] = inbox.getMessages();
for (Message message : messages) {
String subject = message.getSubject();
String location = "AAR|RRC|PSD|TPC|HP|SCC|MCA";
List<String> list = new ArrayList<String>();
System.out.println("SUBJECT: " + subject);
System.out.println("DATE: " + message.getSentDate());
Pattern pattern = Pattern.compile(location);
Matcher match = pattern.matcher(subject);
while (match.find()) {
list.add(match.group());
System.out.println(list);
}
}
} catch (MessagingException e) {
e.printStackTrace();
System.exit(2);
} catch (Exception e) {
e.printStackTrace();
System.exit(2);
}
}
}
I want the program to read each email while searching for the strings saved in locations and store these in an array. This works fine, however I would like each of the abbreviations in the location string be set to an value for determining mileage. I have no idea how I would go about this. In the end I want to be able to sum up all the values from a certain date range of emails based on the numbers found. So, for example, if AAR was set to 15 and showed up in 3 email subject lines and RRC was set to 8 and showed up in 2, it would sum it all up and print it out.

Ended up using:
if(match.group().contains("AAR"){
Then do this string of code
}
It looks pretty sloppy since I have a bunch of if statements but works. Might be better to use a switch instead.

First, correct these common mistakes.
Clearly the server thinks you've supplied the wrong username and password. If you turn on session debugging, you may find more clues as to what the server thinks is wrong. You may also need to set the "mail.debug.auth" property to "true" to see the full authentication protocol exchange.
