case 1 : ImapGmailClient client = new ImapGmailClient();
if the user call the no args constructor the ImapGmailClient will
default to the ImapGmailLabel.INBOX as the source folder.

case 2 : ImapGmailClient client = new
ImapGmailClient(ImapGmailLabel.TRASH);
if the user call the with args constructor , the given
ImapGmailLabel.class enum the ImapGmailClient will default to that
passes argument folder name
ex: ImapGmailLabel.TRASH will set the source folder as [Gmail]/Trash.
