Steps to help you execute a system command via java program:

  1. create user and give him rights to execute systemctl command, see this thread allowing user to run systemctl/systemd services without password

  2. execute your java program using this user

  3. your java code should be: Runtime.getRuntime().exec(new String[]{"systemctl", "stop", "appService.service"});

the first argument is the command to execute, others are the arguments

There is one way also. Create new user with LimitedRoot capabilities and use VISUDO to allow the user to run systemctl/systemd services without entering a password.

Example:

%LimitedRootUser ALL=NOPASSWD: /bin/systemctl restart appService.service
