You can do it this way :-
     public static void main(String args[]) throws Exception {
          ProcessBuilder builder = new ProcessBuilder("ipconfig", "/all");
          Process process = builder.start();
          BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
          FileWriter writer = new FileWriter(new File("C:/ipconfig.txt"));
          String str;
          while ((str = reader.readLine()) != null) {
               System.out.println(str);
               writer.write(str + System.getProperty("line.separator"));
          writer.close();
          reader.close();
     }Let me know if it works for you.
