           Thread commandLineThread = new Thread(() -> {
            try {
                BufferedReader br=new BufferedReader(
                        new InputStreamReader(
                                process.getInputStream()));
                String line;

                while((line=br.readLine())!=null){
                    System.out.println(line);
                }
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        });
        commandLineThread.setDaemon(true);
        commandLineThread.start();
