Java- Scanner V.S. BufferedReader

code sample

1. import file content by BufferedReader

File stopWords = new File("data/stopWords.gold");
            BufferedReader bReader = new BufferedReader(new FileReader(stopWords));
            String fileString = "";
            String lineString = bReader.readLine();
            while (lineString != null) {
                fileString += lineString;
                lineString = bReader.readLine();
            }
            bReader.close();

2. import file content by Scanner and process it

private void checkWords() {
        File file = getInputFileNameFromUser();
        try {
            Scanner scanner = new Scanner(file);
            scanner.useDelimiter("[^a-zA-Z]+");
            while (scanner.hasNext()) {
                String tk = scanner.next();
                tk = tk.toLowerCase();
                if (!dictionaryHashSet.contains(tk)) {
//                  System.out.println(tk + " is not in the dictionary.");
                    corrections(tk.toLowerCase(), dictionaryHashSet);
                }
            }
            scanner.close();
        } catch (FileNotFoundException e) {
            // TODO: handle exception
            System.out.println(e.getMessage());
        }
    }
