本文实例讲述了Java基于IO流读取文件的方法。分享给大家供大家参考，具体如下：

public static void readFile(){ String pathString = TEST.class.getResource("/simu").getFile(); try { pathString = URLDecoder.decode(pathString, "utf-8"); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } System.out.println(pathString); File file = new File(pathString,"test.txt"); InputStream is = null; try { is = new FileInputStream(file); } catch (Exception e) { e.printStackTrace(); } BufferedReader br = new BufferedReader(new InputStreamReader(is)); StringBuffer sb = new StringBuffer(""); String b = ""; try { while((b=br.readLine())!=null){ sb.append(b).append("n"); } } catch (Exception e) { e.printStackTrace(); } String bb = sb.toString(); System.out.println(bb); }

希望本文所述对大家Java程序设计有所帮助。
