1.按行读取
File file = new File(“your path”); BufferedReader reader = null; try { //System.out.println("以行为单位读取文件内容,一次读一整行:"); reader = new BufferedReader(new FileReader(file)); String tempString = null; // 一次读入一行,直到读入null为文件结束 while ((tempString = reader.readLine()) != null) { System.out.println(tempString); // your code } } catch (IOException e) { e.printStackTrace(); } finally { if (reader != null) { try { reader.close(); } catch (IOException e1) { } } }
