Как выполнить команду терминала Windows через программу Java?

Question

Невозможно запустить программу, которая выполняет команду терминала Windows 7.

public class CmdExecutionService {

    public static void main(String[] args) {
        //should change to "demo" directory
        new CmdExecutionService().execute("cd C:\\demo"); 
    }

    public String execute(String cmd) {
        try {
            Process process = Runtime.getRuntime().exec(cmd);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
            reader.close();
            return line;
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
    }

}
