Answer 1

Sorry, this < was the wong way around
Process p=r.exec("java filename >test.txt")
Then read in data from test.txt, something like this should do it :))   public String getTextFile(String text) throws Exception{
      int reader = 0;
      text = "";
      FileReader in = new FileReader("test.txt");
         do {
            reader = in.read();
            text += (char)reader;
         }  while (reader != -1);
      in.close();
      return text;
