Remote shutdown help needed!

Hello all, I'm new to the forum and would really appreciate some help in writing code to remotely shutdown another laptop. Here is the code so far:

Code :

---

import java.io.IOException;
 
class remoteSD {
    public static void main(String[] args) throws IOException {
        Runtime.getRuntime().exec("shutdown /s /m <comp name here>);
    }
}

---

I get no errors but nothing happens... What exactly am I doing wrong? Any help would be greatly appreciated.

Wouldn't a script be more suitable?
