How am I to execute a command in Java with parameters?

I've tried

```
Process p = Runtime.getRuntime().exec(new String[]{"php","/var/www/script.php -m 2"});

```

which doesn't work.

```
String[] options = new String[]{"option1", "option2"};
Runtime.getRuntime().exec("command", options);

```

This doesn't work as well, because the `m` parameter is not specified.
