            BufferedReader reader = new BufferedReader(new FileReader("text.txt"));
            String line;
            while ((line = reader.readLine()) != null) {
                // 处理每一行文本
            }
            reader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

    public static void main(String[] args) {
        try {
            Scanner scanner = new Scanner(new File("text.txt"));
            while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                // 处理每一行文本
            }
