What is the difference between running by creating a process and running through command line?

Question

I have a jar file. I am running this jar file by creating a process. So, what is the difference between running it through command prompt without creating a process? Will it affect the application's performance?

Could you please explain,what do you mean by creating a process? — Ankit Tripathi, Sep 16 '16 at 06:41
Process gateProcess = Runtime.getRuntime().exec(command); so here I am running external jar by creating a process — ganesh, Sep 16 '16 at 06:46

If your application requires you to run the jar file as a command in a separate process from your java application,It's the way to go.There is no question of performance. However when you launch command prompt through Runtime.exec(),command line will be executed as a sub-process or a separate process in a random layer. I'd rather recommend you to use ProcessBuilder,however it's a different topic.

For difference between Runtime.exec() and ProcessBulilder please go through this
