> {code}
> Reader fileReader = new InputStreamReader(
> new FileInputStream(file), Charsets.UTF_8);
> BufferedReader bufferedReader = new BufferedReader(fileReader);
> List<String> lines = new ArrayList<String>();
> String line = null;
> while ((line = bufferedReader.readLine()) != null) {
> lines.add(line);
> }
> bufferedReader.close();
> {code}
> Since bufferedReader.readLine() may throw IOE, so the close of bufferedReader
> should be enclosed within finally block.
