I would strongly advice using library here but since Java 8 you can do this also using streams.

    try (InputStreamReader in = new InputStreamReader(System.in);
         BufferedReader buffer = new BufferedReader(in)) {
        final String fileAsText = buffer.lines().collect(Collectors.joining());
        System.out.println(fileAsText);
    } catch (Exception e) {
        e.printStackTrace();
    }

You can notice also that it is pretty effective as joining is using StringBuilder internally.
