Getting different message count for some mail boxes in a particular account

Question

Hello,
I am using java mail api in my project.
I am using two methods
Case 1 :
folder.getMessageCount()
case 2:
getMessageCount(String folderName){
int iCount = 0;
Folder objFolder = store.getDefaultFolder();
if (folderName != null && folderName.equalsIgnoreCase("") == false) {
objFolder = objFolder.getFolder(folderName);
iCount = objFolder.getMessageCount();
return iCount;
I am getting different output from both the above cases.
I have tested both cases on many accounts and they give me same message count. but for one gmail account only they give me different message count for two folders, Inbox as well as Gmail/All.
Can anyone tell me the reason for this difference.

Answer 1

Yes, in case 1, i first open the folder and then i call folder.getMessageCount().
I am using IMAP in both the cases
as i used Store store = session.getStore("imaps");
Yes, there is no new mail delivered to the folder when this methods are analyzed.
i am getting different count as
imap.getMessageCount() >> First way
imap.getMessageCount(Bi testing) >> Another way:-
imap.getMessageCount(Bi testing)--> Count = 4
imap.getMessageCount()--> Count = 4
imap.getMessageCount(INBOX)--> Count = 125
imap.getMessageCount()--> Count = 117
imap.getMessageCount(Personal)--> Count = 11
imap.getMessageCount()--> Count = 11
imap.getMessageCount(Receipts)--> Count = 6
imap.getMessageCount()--> Count = 6
imap.getMessageCount(Travel)--> Count = 36
imap.getMessageCount()--> Count = 36
imap.getMessageCount(Work)--> Count = 2
imap.getMessageCount()--> Count = 2
*imap.getMessageCount([Gmail]/All Mail)--> Count = 180*
imap.getMessageCount()--> Count = 161
imap.getMessageCount([Gmail]/Drafts)--> Count = 0
imap.getMessageCount()--> Count = 0
imap.getMessageCount([Gmail]/Sent Mail)--> Count = 40
imap.getMessageCount()--> Count = 40
imap.getMessageCount([Gmail]/Spam)--> Count = 0
imap.getMessageCount()--> Count = 0
imap.getMessageCount([Gmail]/Starred)--> Count = 0
imap.getMessageCount()--> Count = 0
imap.getMessageCount([Gmail]/Trash)--> Count = 15
imap.getMessageCount()--> Count = 15
In this two folders Inbox as well as [Gmail]/All Mail showing different counts when used on both methods.
