run script from specific location programatically

Question

I have a java class that runs any scripts on my server i require, and it works nicely.

I have an issue however, i need to run one script from a specific location and not sure how to do that. Is there a way to 'cd' to a directory before running my script in my java method?

My current method:

public String runScriptFile(String pathname) throws IOException{
    Runtime rt = Runtime.getRuntime();
    String output="";
    Process proc = rt.exec(pathname);

    BufferedReader stdInput = new BufferedReader(new 
         InputStreamReader(proc.getInputStream()));

    BufferedReader stdError = new BufferedReader(new 
         InputStreamReader(proc.getErrorStream()));

    String s = null;
    while ((s = stdInput.readLine()) != null) {
        output+=s;
    }

    while ((s = stdError.readLine()) != null) {
        output+=s;
    }
    return output;
}

Answer is to use the location param in Runtime.exec as follows

Process proc = rt.exec(pathname, null, new File("C:\\files\\"));
