Java method of reading files based on IO stream

The example in this article describes Java's method of reading files based on IO streams. Share it with everyone for your reference, the details are as follows:

 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);}

I hope this article will be helpful to everyone in Java programming.
