It feels like a dumb question to ask, but i cant seem to figure it out. when i run a *.jar file on windows it doesnt apears in the taskmanager processes. how can i terminate it
In windows task manager you will see process called "java.exe". Kill that process your application will get stop.
To know the process first go to applications in task manager and then go to process by selecting that application. It will lead you to exact process of that application.
