Keeping a java app going when ssh is closed on Google Cloud

Right now I'm ruing a java app by SSH-ing to a VM on Google Cloud Compute. I issue a command to run the app and it loads a console. As soon as I terminate the SSH coection, the app shuts down. I assume this is because the console has been closed. I would like this app (which is a server) to persist after I terminate SSH, and, at any point, I would like to be able to recoect to the console and issue commands on the server.

Thank You!
