Run a .exe file with parameters from my java code

Hi, I want to run a .exe file from my java program. This .exe file will take some parameters in the command line. I need
to supply that to the program as well. Can someone help me in this please?
Thanks in advance.

I am trying like this:
public class lauch_ext {
     public static void main(String[] args) throws Exception{
          try {
            Runtime rt = Runtime.getRuntime();
            Process pr = rt.exec("C:\\Apps\\myapp.exe arg1 -arg2 return_arg");
            BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
            String line=null;
            while((line=input.readLine()) != null) {
                System.out.println(line);
            int exitVal = pr.waitFor();
            System.out.println("Exited with error code "+exitVal);
        } catch(Exception e) {
            System.out.println(e.toString());
            e.printStackTrace();
}
