How to get the list of available folders in a mail account using JavaMail
I am using JavaMail API to connect to my personal account. I have list of folders (labels) in my Gmail account which I created + the default folders like Inbox, Drafts etc. How can I list all the available folders (the default and the user created)?
I can access the particular folder using this API:
Folder inbox = store.getFolder("Inbox");
Here is the code that works. This will give you handle to all the Labels. To go deeper in a folder, you may perform folder.list() or you can use store.getDefaultFolder().list("*") to retrieve all the folders and sub-folders as suggested in the other answer.
Properties props = System.getProperties();
props.setProperty("mail.store.protocol", "imaps");
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com", "YOURMAILID@gmail.com", "UR_P@ZZWRD");
System.out.println(store);
Folder[] f = store.getDefaultFolder().list();
for(Folder fd:f)
System.out.println(">> "+fd.getName());
Output:
>> INBOX
>> Personal
>> Receipts
>> Travel
>> Work
>> [Gmail]
