读写txt文件

读取txt文件：

/** * 读取txt文件的整行 * @return * @throws IOException */public List<String> read(String fileName) throws IOException {List<String> txtList = new ArrayList<String>();BufferedReader in = new BufferedReader(new FileReader(fileName));String line = null;while ((line = in.readLine()) != null) {txtList.add(line);}return txtList;}

?写入txt文件：

/** * 将"Hello world！"写入txt文件（"Hello world！"可以换为字符串） * @param fileName txt文件路径 */public void writeTpTxt(String fileName) {try {File file = new File(fileName);FileWriter fw = new FileWriter(file);BufferedWriter bw = new BufferedWriter(fw);bw.write("Hello world！");bw.close();} catch (IOException e) {e.printStackTrace();}}
