ProcessBuilder does not work?

Question

I'm trying add a key register on windows using ProcessBuilder. Before I tried Runtime.getRuntime.exec() and doesn't work also.

I'm trying this.

ProcessBuilder p = new ProcessBuilder("reg add HKCU\\Software\\Microsoft\\Windows /v mykey /t REG_SZ /d " + "key_value");
        try {
            p.start();
        } catch (IOException ex) {
            Logger.getLogger(Registro.class.getName()).log(Level.SEVERE, null, ex);
        }

The exception is:

GRAVE: null
java.io.IOException: Cannot run program "reg add HKCU\Software\Microsoft\Windows /v mykey /t REG_SZ /d key_value": CreateProcess error=2, O sistema não pode encontrar o arquivo especificado

    ... 2 more

Any idea ?

@Jarrod Roberson is right. You should use:

Process p = Runtime.getRuntime().exec("reg add HKCU\\Software\\Microsoft\\Windows /v mykey /t REG_SZ /d " + "key_value");
