I am developing a Java app that reads all the emails from GMAIL and save them run time on objects of self made Class that holds some of the attributes of the email. Now I want to delete an email object and when I do that I want it to be removed from the internet as well. In order to do so I will need some information to query the GMAIL account to delete that particular email I am referring to. Is there a possible way to do that? Maybe by saving the header and then searching for that? I couldn’t find a good way to do it.

I assume you are accessing GMAIL with IMAP. Then you could store the Message, call Message.setFlag(Flag.DELETED) then expunge the Folder, or search the Folder yourself. Or maybe you can search the Google Gmail api and find a better way. For example you can use the unique message ID
UPDATE this is a google project that can help you: java-gmail-imap. There is also a companion project for OAuth authentication (needed for run the sample)
