java读写文件

读：

try {InputStream in = new FileInputStream(file);BufferedReader br = new BufferedReader(new InputStreamReader(in,"utf-8"));String s = null;while((s = br.readLine())!=null){//使用readLine方法，一次读一行result = result + "\n" +s;}System.out.println(result);br.close();  }  catch (IOException e) {e.printStackTrace();}

写：

try {String strEncode="UTF-8";BufferedWriter bufWriter = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file), strEncode));bufWriter.write(result);  bufWriter.close();} catch (IOException e) {e.printStackTrace();}
