JAVA 读取文件的每一行数据

       ArrayList<String> arrayList = new ArrayList<>();
        try {
            File file = new File("E:\\new1.txt");
            InputStreamReader inputReader = new InputStreamReader(new FileInputStream(file),"UTF-8");
            BufferedReader bf = new BufferedReader(inputReader);
            // 按行读取字符串
            String str;
            
            while ((str = bf.readLine()) != null) {        
                arrayList.add(str);
            }
            bf.close();
            inputReader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
