When a program/process is started in bash without nohup, is it later possible to let this program run even after the shell/terminal is closed

When a program/process is started in bash **WITHOUT** nohup, is it later possible(do something further) to let this program run even after the shell/terminal is closed. Here is a great discussion on Difference between nohup, disown and & if any one is interested in refering. **In this question i want to share my observation about when a program is started without nohup.** Edit - Please ignore the orginal Q. Yes after disowning the process, killing the terminal/shell does not seem to matter. The process seems to run. With ps -ef | grep java I am able to see the process running even after the original terminal is closed.
