I have installed java on my machine, so I tried to use command

just troubleshooting here.

did you set the permission so the file can run as a program?

I am quite new to Linux. How to set permission so I can run the jar file as a program?

it sounds like you are in the wrong directory when you execute the command, or that the jar file is not where you think it is. try ls from the shell to see the file listing. also you can try sudo chmod +x yourjar.jar to give it execution permission to the file.
