java(IO)读写文件乱码转换UTF-8问题

     读取文件String Content = ""; // 文件很长的话建议使用StringBuffertry {FileInputStream fs=new FileInputStream("文件录取");InputStreamReader isr = new InputStreamReader(fis, "UTF-8");BufferedReader br = new BufferedReader(isr);String line = null;while ((line = br.readLine()) != null) {Content += line;Content += "\r\n"; // 补上换行符}catch (Exception e) {         e.printStackTrace();}  写入文件

   public static void outFile(String sb) {try {File file = new File("G:\\liuhecai.txt");if (file.exists()) {file.delete();}file.createNewFile();FileOutputStream fos = new FileOutputStream(file);OutputStreamWriter osw = new OutputStreamWriter(fos, "utf-8");osw.write(sb);} catch (UnsupportedEncodingException e) {e.printStackTrace();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}
