    String line;
    Process process = Runtime.getRuntime().exec("ps -e");
    process.getOutputStream().close();
    BufferedReader input =
            new BufferedReader(new InputStreamReader(process.getInputStream()));
    while ((line = input.readLine()) != null) {
        System.out.println(line); //<-- Parse data here.
    }
    input.close();

We have to use process.getOutputStream.close() otherwise it will get locked in while loop.
