Is it possible to find a message not read using the java mail API?

Question

I used java mail to read Gmail as follows:

Session session = Session.getDefaultInstance(props, null); Store store = session.getStore("imaps"); store.connect("imap.gmail.com", "mail", "password"); Folder folder = store.getFolder("INBOX"); folder.open(Folder.READ_WRITE); Message[] messages = folder.getMessages(); 

Now I want to find out if the message is unread, but cannot find any API. I want to do something like:

  for(Message message:messages) { if(message.isUnread) { // Do Something here } } 

There is no such API yet - isUnred.

Have you tried Message.isSet (Flags.Flag.SEEN)

This message is visible. This flag is implicitly set by the implementation when the contents of this message are returned to the client in some form.

It has been a while since I used JavaMail, but I think that does what you want
